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

aimThe aim was to explore the preventive effects of smartphone cognitive behavioral therapy (CBT) in addressing depression and anxiety in patients with recurrent pregnancy loss (RPL) due to lack of such previous studies.

methodsThis was an exploratory decentralized, parallel-group, multicenter, open, individually randomized, fully factorial trial. A total of 432 patients with RPL were randomized and patients who completed the psychoeducation component of the app within 2 weeks of consent were included. Five CBT components-namely, self-monitoring, behavioral activation, cognitive restructuring, assertion training, and problem solving-were randomly assigned as present or absent, resulting in 2

resultsA total of 419 patients were analyzed. The presence or absence of specific CBT components did not significantly affect patient outcomes. However, patients experienced a statistically significant overall reduction in depressive symptoms from baseline to weeks 8 and 12. Pre-post effect sizes for overall improvement ranged from -0.30 to -0.38 at week 8 and from -0.22 to -0.33 at week 12. No significant overall reduction in anxiety symptoms was observed.

conclusionThe CBT application significantly reduced depressive symptoms in patients with RPL; however, no specific CBT component showed superior effects. The findings did not indicate efficacy in comparison to the pure treatment-as-usual group. Further research is required to enhance its impact on anxiety and refine the selection and delivery of individual CBT components.
