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

purposeYoung people living in slums are at increased risk of poor mental health. We examined the prevalence and correlates of mental disorders among youth living in slums in low-and middle-income countries (LMICs).

methodsA search of seven databases (MEDLINE, Embase, PsycINFO, Scopus, Web of Science, CINAHL, and African Journals Online) was conducted from inception to September 2022 and updated to March 2026. Studies were screened by two independent reviewers who also extracted data and assessed the study quality and risk of bias using the Joanna Briggs Institute critical appraisal tool (JBI). Meta-analyses were carried out using the random effects model (REML) to estimate prevalence and 95% CI.

resultsWe identified 24 studies out of 3,946 citations, reporting data on depression, post- traumatic stress disorder (PTSD), anxiety, and alcohol use disorders (AUDs), involving 26,794 participants. The pooled prevalences were depression 31% (95% CI: 0.23-0.40; I

conclusionYoung people living in slums carry a disproportionate burden of mental disorders. There is an urgent need for contextually grounded policies and interventions to mitigate identified risk factors, strengthen protective factors, and break down barriers to treatment for those in need.
