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

objectivesCanadian population-based data show that sexually diverse youth face greater mental health challenges than their heterosexual peers. However, nuances within sexual diversity-particularly among mostly heterosexual persons-are overlooked, and psychotic-like experiences remain underexplored. We examined the mental health of sexually diverse young adults from Quebec, spanning indicators from well-being to psychotic-like experiences.

methodsData were drawn from 1324 youth from the Quebec Longitudinal Study of Child Development-a representative cohort born in 1997/98 and followed up until age 23. Participants self-reported their sexual orientation and mental health across nine indicators: suicidality, depression, anxiety, binge drinking, cannabis, other drug use, psychotic-like experiences, well-being, and help-seeking. Standardized mean differences (SMD) assessed group differences, stratified by assigned sex at birth and sexual orientation.

resultsA total of 324 (24.47%) youth identified as non-heterosexual. These youth reported poorer outcomes across all indicators (SMDs ranged from 0.19 for cannabis use to 0.52 for suicidality) and had higher odds of seeking psychological help (OR = 2.09, 95% CI [1.52-2.89]). Sexually diverse females reported poorer outcomes across all indicators compared to heterosexual females. Sexually diverse males had elevated risks for suicidality, depression, anxiety, and reduced well-being compared to heterosexual males. Mostly heterosexual (N = 156, 48.15%) and bisexual persons (N = 85, 26.23%) reported more symptoms than heterosexuals.

conclusionDespite Canada's inclusive stance on sexual diversity, sexually diverse youth-especially those identifying as mostly heterosexual and bisexual-continue to face significant mental health disparities. Our findings highlight the need for accessible, tailored mental health services to support this population.
