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

introductionThe COVID-19 pandemic has significantly affected adolescents' mental health, raising concerns about the potential increase in self-harming and suicidal behaviors (SIB). This study aimed to evaluate the pandemic's impact on SIB among adolescents and explore the effects of school closures and psychiatric vulnerabilities to inform future interventions.

methodsA systematic review and meta-analysis were conducted using PubMed, resulting in 420 studies, of which 36 studies (comprising 53 samples) met the inclusion criteria, encompassing 1,754,106 adolescents. Effect sizes were calculated using proportion effect size. Heterogeneity across studies was assessed using Q-statistics and I², while Egger's test was applied to evaluate publication bias. Differences between clinical and community samples, as well as the influence of psychiatric symptoms or disorders, were examined.

resultsClinical samples demonstrated higher rates of SIB compared to community samples, with adolescents having psychiatric symptoms or disorders being more vulnerable. Overall, the pandemic was associated with a decline in SIB rates compared to pre-pandemic levels. Suicidal ideation decreased by 4.14% in combined samples and by 7.13% in community samples. Self-harm rates fell by 5.38% and 6.62% in combined and community samples, respectively. In contrast, clinical samples showed a distinct trend, with suicidal ideation decreasing by 29.39%, while self-harm rates increased by 32.51% and suicide attempts rose by 22.41%.

conclusionThe COVID-19 pandemic's impact on adolescents' SIB varied significantly across population types and levels of psychiatric vulnerability. While general declines were observed, the pronounced increases in self-harm and suicide attempts among clinical samples highlight the need for tailored mental health interventions. Addressing these disparities is essential for future mental health strategies and crisis preparedness.
