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

purposeFew studies have examined how psychosocial risk and protective factors in adolescence shape mental health outcomes and other multimorbid conditions in adulthood, particularly among Canadian youth. The Research on Eating and Adolescent Lifestyle (REAL) 2.0 study was a 15-year follow-up cohort study designed to investigate how early etiological factors, including body image and disordered eating symptoms in adolescence, contribute to the development of eating, weight-related concerns, mental health and substance use health problems in early adulthood. In this paper, we describe the REAL 2.0 cohort's demographic and clinical characteristics alongside an overview of the study procedures, laying the groundwork for collaboration on future learnings with this unique data.

participantsThe cross-sectional REAL study initially surveyed middle and high school students from 2004 to 2010 (n=3043) across 43 schools in the Ottawa, Canada region. Of those, respondents in grade 7 or 9 (n=1197 from 25 of the 43 original schools) were asked to participate in a longitudinal arm of the study that consisted of yearly follow-ups. From the longitudinal cohort, there were 278 participants (29.1% male; M FINDINGS TO DATE: 9.4% of REAL 2.0 participants met DSM-5 criteria for an eating disorder, while 17.6% met criteria for disordered eating. Moderate to severe anxiety was reported by 28% of participants, while 21.6% experienced moderate to severe depressive symptoms. Regarding substance use, 16.9% engaged in hazardous drinking, 16.9% used cannabis daily or almost daily, and 4.3% reported daily tobacco use. FUTURE PLANS: REAL 2.0 has the potential to answer multiple research questions about several mental health outcomes, but its priority focus is to answer questions related to risk and protective factors of multimorbidity in adulthood. Additionally, profiling work, linked to health service utilisation data for systems planning work and predictive modelling studies are secondary goals. By leveraging the Health Data Nexus (HDN) platform, we welcome collaboration with interested researchers who would like to utilise the breadth of data both in adolescence and adulthood to answer other pertinent aetiological questions in mental health and substance use health outcomes. Future plans to conduct additional follow-ups remain feasible.
