Longitudinal effects of bushfire harm on adolescent mental health.
Article in The Australian and New Zealand journal of psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundIn Australia, harms associated with bushfires are expected to increase as the severity and frequency of bushfires increase with climate change. Bushfire harm includes negative impacts on mental health, particularly for adolescents. Evidence suggests that elevated incidence of mental illness can persist long-term after bushfire harm. This study extends our team's earlier cross-sectional analysis within the same cohort. It examines effects of the Black Summer bushfires (2019-2020) on adolescents' mental health measured prospectively and explores risk and protective factors associated with sustained mental health problems following bushfire harm.
methodsA broadly representative sample of 2967 Australian adolescents was recruited in 2019-2022 at age 13-14 and followed for 24 months. Bushfire exposure and harm, and symptoms of depression, anxiety, psychological distress, insomnia, and suicidality were measured. Linear regression models examined the effects of bushfires over time; logistic regression identified predictors of these effects.
results167 (5.4%) participants reported bushfire harm. Bushfire harm was not a significant predictor of any mental health outcomes at 24 months. Baseline symptoms were most strongly associated with 24-month outcomes. Participants who were gender or sexuality diverse, reported adverse childhood experiences, or had a history of mental health problems had increased risk of symptoms of depression, anxiety, distress and insomnia at 24-month follow-up compared to those who did not have these risk factors.
conclusionsBushfire-harmed adolescents did not show significantly elevated mental health symptoms compared to unexposed peers 24 months later. This finding is encouraging, though its underlying causes are unclear and require further research.
