Placebo Response in Randomized Controlled Trials of Antidepressants for Pediatric Major Depressive Disorder
Abstract
Objective: The authors examined characteristics and predictors of response to placebo in all available reports of short-term randomized controlled trials of antidepressants for pediatric major depressive disorder. Method: Response, defined as a score ≤2 on the improvement item of the Clinical Global Impression scale, and potential predictors were extracted from 12 published and unpublished randomized controlled trials of second-generation antidepressants in participants 6–18 years of age with major depression. Results: The single best predictor of the proportion of patients taking placebo who responded to treatment was the number of study sites. Baseline severity of illness also emerged as a significant inverse predictor of placebo response, although the strength of this relationship was diminished when number of sites was controlled for. After one large fluoxetine trial was excluded, younger participants showed a higher placebo response rate than older adolescents. Higher placebo response rates in more recent studies were explained by an increasing trend toward large multisite trials and by publication delays and failures to publish some negative trials. Conclusions: The recent shift toward large multisite trials of antidepressant medications for pediatric major depression may be contributing to an increasing incidence of response to placebo. Pharmacotherapy studies of pediatric depression that carefully recruit patients with at least moderately severe depression may be more informative and efficient than many trials conducted to date. Such studies should have sufficient power to determine whether age moderates medication and placebo response.

“methodological issues, including aspects of study design and conduct (i.e., issues with identifying appropriate patients, large multi-site trials, multiple raters) that have been previously proposed as possible reasons for negative clinical trials in MDD”
From A randomized, double-blind, duloxetine-referenced study comparing efficacy and tolerability of 2 fixed doses of vortioxetine in the acute treatment of adults with MDD (2015) · cites this paper as Bridge et al., 2009
In the citing paper
“Thus, considering the substantial control group response that exercise RCTs must overcome to show a benefit in depressive symptoms and the benefits in absolute terms, critiques concerning the efficacy of exercise for depression (e.g., [13]) may be premature, particularly in light of the plethora of other health benefits of an active lifestyle [10, 78, 79].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
