Repeat Self-Harm Following Hospital-Presenting Intentional Drug Overdose among Young People-A National Registry Study.
Article in International journal of environmental research and public health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundThe incidence of hospital-presenting self-harm peaks among young people, who most often engage in intentional drug overdose (IDO). The risk of self-harm repetition is high among young people and switching methods between self-harm episodes is common. However, little is known about their patterns of repetition and switching following IDO. This study aimed to investigate repeat self-harm and method-switching following hospital-presenting IDO among young people.
methodsData from the National Self-Harm Registry Ireland on hospital-presenting self-harm by individuals aged 10-24 years during 2009-2018 were examined. Cox proportional hazards regression models with associated hazard ratios (HRs), survival curves and Poisson regression models with risk ratios (RRs), were used to examine risk factors for repetition and method-switching.
resultsDuring 2009-2018, 16,800 young people presented following IDO. Within 12 months, 2136 young people repeated self-harm. Factors associated with repetition included being male (HR = 1.13, 95% CI: 1.03-1.24), aged 10-17 years (HR = 1.29, 95% CI: 1.18-1.41), consuming ≥ 50 tablets (HR = 1.27, 95% CI: 1.07-1.49) and taking benzodiazepines (HR = 1.67, 95% CI: 1.40-1.98) or antidepressants (HR = 1.36, 95% CI: 1.18-1.56). The cumulative risk for switching method was 2.4% (95% CI: 2.2-2.7). Method-switching was most likely to occur for males (RR = 1.36; 95% CI: 1.09-1.69) and for those who took illegal drugs (RR = 1.63; 95% CI: 1.19-2.25).
conclusionYoung males are at increased risk of repeat self-harm and method-switching following IDO and the type and quantity of drugs taken are further indicators of risk. Interventions targeting IDO among young people are needed that ensure that mental health assessments are undertaken and which address access to drugs.
