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
Objective This study examined whether cannabis expectancies mediate the relationship between lifetime cannabis use and symptoms of anxiety or depression among women who screened positive for post-traumatic stress disorder (PTSD). Method A total of 271 women completed an online survey assessing PTSD symptoms, lifetime cannabis use, anxiety and depression symptoms, and cannabis expectancies. Mediation analyses evaluated whether positive and negative cannabis expectancies explained the associations between lifetime cannabis use and anxiety or depression. Results The sample was predominantly White (238, 85%), with a mean age of 52.5 years (Mean±SD=12.2). Positive cannabis expectancies mediated the relationship between lifetime cannabis use and anxiety [indirect effect=0.35, Bootstrapped standard error of the effect estimate (BootSE)=0.15, 95% confidence interval (CI)=0.076 to 0.664] and depression (indirect effect=0.45, BootSE=0.19, 95% CI=0.12 to 0.88) such that women with longer cannabis use histories reported higher positive expectancies and higher levels of anxiety and depression. Conclusions Positive beliefs about cannabis's anxiolytic and antidepressant effects may influence both the duration of use and psychological outcomes among women with PTSD. These findings highlight the role of expectancies in shaping the mental health impact of cannabis use in this population.
