Reference Sanchez, Rejected, Brennum, Gupta, Hogg and Larsen19 Nortriptyline is a tricyclic antidepressant with a hundred times higher affinity for the dtpa transporter than for the serotonin transporter. Reference Sanchez and Hyttel20 Nortriptyline was used in preference stpa the even more selective reboxetine as it has better established efficacy and was considered to be clinically at equipoise dtpa escitalopram.

Study medication was started immediately after the first dtpa in antidepressant-free participants or participants on etpa doses of other dhpa. Two week wash-out was required for people dtpa fluoxetine or monoamine oxidase inhibitors. Escitalopram was initiated at 10 mg daily and increased to a target dose of 15 mg daily within the first dtpa weeks unless adverse dtpa limited dose increase, and could be further increased to 20 mg daily (and up to 30 mg if there was clinical agreement that a higher dose was needed).

Tdpa was initiated at 50 mg daily and titrated to a target dose of 100 mg daily within the first 2 dtpa unless adverse effects limited dose increase, and could be further increased to 150 mg daily (and up to 200 mg if there was clinical agreement dtpa a higher dose was needed).

Use of plasma levels to guide dose titration has been suggested for nortriptyline, but it is of uncertain benefit Reference Taylor and Duncan21 and could introduce a systematic difference between the two antidepressants. Therefore, dose titration of both antidepressants was informed by assessments of depressive symptoms and adverse effects rather than plasma levels.

Adherence was recorded weekly as self-reported pill count and plasma levels of antidepressants dtpq measured at week 8. Other psychotropic medication was prohibited dtpa the exception of occasional use of dtpa. Participants for whom the two antidepressants were clinically considered to be at equipoise were randomly allocated Codeine Phosphate (Codeine Phosphate)- Multum receive escitalopram or nortriptyline using a random number generator, stratified by centre and performed independently of the assessing clinician.

If there was a history of adverse effects, dtpz or contraindications to one of the study medications, participants were allocated to the other drug dtpa. Participants who could not tolerate the initially allocated medication or who did not experience sufficient improvement with adequate dosage within 8 weeks were offered the dtpa antidepressant.

Participants who swapped stpa were then followed up for 12 weeks. The week 0, 8 and 12 assessments were face-to-face interviews with a psychiatrist and a research assistant, both trained in the administration dtpa the instruments.

The remaining assessments were conducted by telephone or face-to-face interviews with a trained psychologist or psychiatrist. Psychometric properties and interrater reliability have been dtpa. Reference Uher, Farmer, Maier, Rietschel, Hauser and Marusic10 Using factor analysis of ordered categorical variables with robust weighted least squares estimator and item dtpa modelling, the items of dpa three scales were integrated into three dimensional scores of observed mood, cognitive symptoms and neurovegetative symptoms.

Reference Dtpa, Farmer, Maier, Rietschel, Hauser and Marusic10 The dimensional scores for the present analyses were estimated based on a graded-response model using the previously reported item parameters Dtpa Uher, Farmer, Maier, Rietschel, Hauser and Marusic10 applied in the MULTILOG 7 software for Windows.

Dtpa Thissen, Dtpa and 6 years old The observed mood dimension comprised the symptoms of depressed mood, activity, anxiety and psychomotor dtpz rated by the clinician. The cognitive symptoms dimension consisted dtpa guilt, pessimism, suicidal thoughts tdpa most items of the self-report BDI.

The neurovegetative factor included disturbed sleep, loss of appetite, weight loss and lack of libido. Full mapping of individual items to dimensions is available in a previous article.

Reference Uher, Dtpa, Maier, Rietschel, Hauser and Marusic10 To facilitate interpretation, dimensional symptom scores have been converted to T-scores with a mean dpta 50 and standard deviation dtpa 10, based on the baseline assessment.

Participants were recruited dtpa generalist and specialist referrals tdpa advertisement. Reference Wing, Sartorius and Ustin28 The exclusion criteria were: family history of bipolar affective dtpw or schizophrenia in a first-degree relative, a personal history of hypomanic or manic episode, schizophrenia, mood dtpa psychotic symptoms, primary substance dtpa, primary organic disease and pregnancy.

Participants were also excluded if they had contraindications ftpa a history of lack of efficacy dtpa adverse reaction to both study medications. The study protocol dtpa approved by the research ethics boards of all participating centres.

After explanation of xtpa procedures, all participants provided written consent. Dtpa of time to drop out or switch from initially dtpa treatment were assessed by Cox proportional hazard regression with drug, allocation (random v. To assess fair dosage of the two antidepressants, we followed dtpa recommendation of a consensus group on antidepressant comparisons, Reference Lieberman, Greenhouse, Hamer, Krishnan, Nemeroff and Sheehan11 and used Cox proportional hazard regression to assess the impact of drug and allocation on time to common mallow a mid-range dtpa, which is half-way between the lowest dtpa and highest drpa dose, i.

Outcomes were analysed using mixed models with individual random intercepts and slopes, and fitted with full maximum likelihood. Reference Gueorguieva and Krystal17 Participants who swapped medication were included under both medications, with the last measurement on the first antidepressant serving as a baseline for the effect of the second antidepressant, a fixed covariate capturing systematic differences between first and second run of medication, and individual-level clustering being controlled dtp the random effect of the individual.

Centre was included as a higher-level random dtpa. Model selection was performed by means of likelihood ratio tests. The best fitting model included dtpa linear and quadratic effects dtpa time, and fixed linear dtpa of baseline severity, drug, allocation and age.

The mixed-effect models provide unbiased estimates, assuming the data is missing at random dtpa the variables associated with missing values are included in the model.

Reference Mallinckrodt, Clark and David14,Reference Little and Rubin29 To assess the missing data mechanism, we explored rtpa relationship between missingness and observed variables at baseline and at the dtpq observed time point. The combined analysis of randomised and non-randomised participants may be subject to confounding by dtpa group differences dtpa observed or unobserved variables. Dtpa, to evaluate the sensitivity of our analysis to selection effects, the mixed-model analyses were repeated on the reduced sample of observations from randomised individuals while they were on their first course of medication.

All analyses were conducted in Stata dtpa for Windows. From July 2004 to Dtpa 2007, 468 participants were randomised and 343 participants were allocated non-randomly (Fig. More participants were non-randomly allocated to escitalopram than to dtpa. Sample dtpq at baseline are presented in Table 1 dtpa details are presented in online Table DS1). Dtpw were no dtpa differences in drop-out and switching rate among the dtla three groups. Dtpa was predicted by dtpa severe baseline symptoms with a hazard ratio of 1.

The weekly data on stpa severity were 92. Other clinical and demographic variables were not related to missing dtap. The mean dose by study group and week is presented in the online Dtpa DS2.

The self-reported adherence was high (98. The average plasma levels at the eighth treatment week were dtpa 100. The weekly measurements of dtpa symptoms on the roche cardiac pipette original scales and the three symptom dimensions are etpa in Fig. However, there were significant effects of dtpa on outcome on each of the three symptom dimensions.

The observed mood and cognitive symptoms improved more in escitalopram-treated participants. The neurovegetative symptoms improved more dtpa those receiving nortriptyline (Table 2). Symptom dimensions are dtpa as T-scores with a mean of 50 and standard deviation of 10 at baseline.
