A Meta-Research of Randomized Controlled Trials in the Field of Mental Health: Comparing Pharmacological to Non-Pharmacological Interventions from 1955 to 2020.
Article in Canadian journal of psychiatry. Revue canadienne de psychiatrie, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to provide a general overview of mental health randomized controlled trials (RCTs) and summarize the temporal trends in terms of the number of studies, median sample sizes, and median effect sizes using data collected from the Cochrane Database of Systematic Reviews (CDSR).
methodsUsing data collected from the CDSR, the temporal trends are compared in terms of the number of studies, median sample sizes, and median effect sizes between two broad categories of interventions: pharmacological RCT (ph-RCT) and non-pharmacological RCT (nph-RCT), and in conjunction with major mental disorder categories.
resultsChronologically, the number of mental health RCTs reported in publications has increased exponentially from 1955 to 2020. While ph-RCT comprised a majority of mental health RCTs in the earlier years, the proportion of nph-RCTs increased more quickly over time and markedly exceeded ph-RCT after 2010. The median sample size for all 6,652 mental health RCTs was 61, with 61 for ph-RCT and 60 for nph-RCT. Over time, the median fluctuated but an increasing trend was observed over the past 60+ years. The median of the effect size, measured by Pearson's
conclusionsThis study provides meaningful information and filled the knowledge gap in mental health RCTs.
