Temporal trends and patterns in suicidal ideation among adolescents in 23 countries from 2003 to 2021.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Although suicidal ideation is a significant issue among adolescents, previous studies have largely relied on cross-sectional data collected at a single time point or have been limited to individual countries, providing limited insight into temporal trends across diverse populations. Therefore, we aimed to examine temporal trends in suicidal ideation among adolescents across 23 countries. We analyzed data from the Global School-Based Student Health Survey (2003-2021), which included adolescents aged 13-15 years in 23 countries. Each participant participated in multiple surveys, and survey years varied by country. Prior to trend estimation, we compared linear and quadratic fits where more than three surveys were available to identify near-linear patterns. Temporal trend was quantified as the average annual percentage change (AAPC), which was calculated by weighted log-linear regression on the log prevalence rates of the survey years, applied separately to boys and girls. The study analyzed 185,941 school-attending adolescents (46.45% male) across 23 countries. The prevalence of suicidal ideation showed significant upward trends in six countries: Myanmar (AAPC, 32.04%/year; 2007-2016), Guyana (AAPC, 8.88%/year; 2010-2014), Saint Vincent and the Grenadines (AAPC, 3.87%/year; 2007-2018), Mongolia (AAPC, 3.67%/year; 2010-2013), Bolivia (AAPC, 3.02%/year; 2012-2018), and Seychelles (AAPC, 2.54%/year; 2007-2015). Conversely, five countries exhibited significant declines, including Benin (AAPC, -8.60%/year; 2009-2016), Kuwait (AAPC, -6.40%/year; 2011-2015), and the Maldives (AAPC, -4.33%/year; 2009-2014). Sex-specific differences in trends were nominally significant (p < 0.05) in six countries-Benin, Kuwait, Argentina, Saint Vincent and the Grenadines, Thailand, and Guyana-but only two (Saint Vincent and the Grenadines and Thailand) remained statistically significant after Bonferroni correction. In five of these countries (excluding Guyana), girls exhibited more unfavorable patterns, showing either a greater increase or a smaller decrease in suicidal ideation compared to boys. This study highlights divergent trends in adolescent suicidal ideation across 23 countries, with rising prevalence in some regions and notable sex differences. The findings underscore the need for continued surveillance and context-specific mental health interventions.
