1 · What the graph read from it

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.

2 · The registry

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

The co-occurrence of depression with posttraumatic stress disorder (PTSD) is common and associated with greater severity and impairment than PTSD alone, but the effects on PTSD treatment outcomes are unclear. This study investigated the impact of baseline depression on PTSD symptom change and dropout in a meta-analysis of 44 randomized controlled trials (N = 4,866) of trauma-focused psychotherapies for PTSD. Analyses included 107 active (k = 71) and control (k = 36) conditions. Baseline depression was indexed within samples as (a) continuous symptom severity (e.g., Beck Depression Inventory), standardized across depression measures and (b) proportion of patients with comorbid depressive disorder diagnosis. Among active conditions reporting continuous depression scores (k = 62), greater depression severity predicted smaller PTSD treatment effect sizes (ß = -.36, p = .002), but not dropout (ß = .25, p = .18). Categorical depressive diagnosis rates (k = 29)-reported less frequently-were not associated with treatment effects or dropout in active conditions. Greater depression severity may reflect a risk factor for attenuated response in PTSD psychotherapies, potentially demanding complementary strategies within trauma-focused interventions. Variability between trials in baseline depression symptoms may suggest the need to consider this sample characteristic when comparing treatment outcomes across studies.
