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

objectiveRates of suicide, suicidal ideation and self-harm are higher in regional and remote areas of Australia. This study aimed to examine the regional co-occurrence of adolescent suicidal ideation/self-harm and adverse childhood experiences, with consideration of area-based indices of socio-economic disadvantage and remoteness and the availability of mental healthcare professionals in New South Wales (NSW).

methodsParticipants were 73,883 young people, born between 2002 and 2005, represented in the NSW Child Development Study (NSW-CDS) - a record-linkage study utilising Commonwealth and State government records. Aggregated longitudinal data according to statistical areas of residence were used to geographically map adolescent suicidal ideation/self-harm against prior adverse childhood experiences, socio-economic disadvantage, geographical remoteness and the number of mental healthcare professionals per region.

resultsThe average number of adverse childhood experiences and the proportion of children residing in areas of socio-economic disadvantage and geographical remoteness were strongly associated with the regional incidence of suicidal ideation/self-harm. Associations between the incidence of suicidal ideation/self-harm and the number of mental healthcare professionals in each region were not significant in adjusted models. Young people growing up in regions outside of Greater Sydney, particularly those in north-west NSW, had the greatest exposure to early adverse childhood experiences, the highest proportion residing in socio-economic disadvantaged and geographically remote areas and the highest incidence of adolescent suicidal ideation/self-harm. DISCUSSION: These findings have policy implications for the geographic allocation of resources to prevent self-harm and suicide in young people. Early-life interventions should be aimed at reducing adverse childhood experiences.
