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

purposeChildhood injuries have been associated with mental health problems such as acute stress disorder and post-traumatic stress disorder, possibly due to exposure to childhood adversity, but few studies have investigated a longer-term psychological impact of childhood injury. This study aims to investigate the link between unintentional injury and adolescent mental health.

methodsSecondary data analysis of 7,264 children in Millennium Cohort Study. Mental health was measured in the sixth sweep of the study when the children were 14 years old; unintentional childhood injuries were measured in each of the first five sweeps at age 9 months, 3, 5, 7, and 11 years old.

resultsAfter controlling for relevant variables, an association between experience of multiple injuries in childhood and poor mental health in adolescence remained (OR = 1.31, 95% CI = 1.05-1.64). However, stratified by sex, only girls who experienced multiple injuries had an increased risk of poor mental health in adolescence (OR = 1.62, 95% CI = 1.17-2.24).

conclusionUnintentional injury experienced in childhood is associated with poor mental health in adolescent females only. We discuss the potential mechanisms for this finding, including the possible different association between injury and wider adversity by sex, and measurement artefacts. More research is needed to investigate the mechanisms and the relationship between multiple injuries and the wider experience of adversity in childhood.
