Premature Mortality in Patients With Anorexia Nervosa: A Matched Cohort Study of Cause of Death.
Article in The International journal of eating disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo determine the extent to which anorexia nervosa is associated with premature mortality.
methodWe carried out a matched cohort study of 7332 male and female patients with anorexia nervosa and 73,215 patient controls who were admitted between 1989 and 2023 in hospital centers of Quebec, Canada. We tracked the patients longitudinally over time to identify premature deaths before age 75 years and determined the cause of death. We used stratified Cox regression models adjusted for patient characteristics to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association between anorexia nervosa and premature mortality.
resultsOverall, 186 (2.5%) patients with anorexia nervosa and 615 (0.8%) matched controls died before age 75 years. Compared with no anorexia, anorexia nervosa was associated with 3.02 times the risk of premature mortality among females (95% CI 2.50-3.65) and 2.23 times the risk among males (95% CI 1.35-3.70). Patients with a first anorexia nervosa admission between age 20 and 29 years were most at risk of premature mortality (HR 8.00, 95% CI 4.30-14.88), as were patients hospitalized ≥ 3 times for anorexia nervosa (HR 4.72, 95% CI 3.25-6.84). Anorexia nervosa was associated with premature mortality due to metabolic and other endocrine disorders, suicide, and a range of other causes. DISCUSSION: Anorexia nervosa is associated with an elevated risk of premature mortality from metabolic disorders, suicide, and other causes. Patients who are female, hospitalized as young adults, or have repeated admissions for anorexia nervosa are most at risk.
