Eating disorders and subsequent risk of substance use disorders involving illicit drugs: a Danish nationwide register-based cohort study.
Article in Social psychiatry and psychiatric epidemiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeNo study has investigated the ongoing risk of substance use disorders involving illicit drugs (ISUD) after first eating disorder (ED) and whether the pattern of risk differs according to types of ED and ISUD. Therefore, we aimed to longitudinally assess the risk of a subsequent diagnosis of any ISUD (pooled category) and specific ISUD after a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED).
methodsA retrospective cohort study using data from Danish nationwide registers identified 20,759 ED patients and 83,038 matched controls (1:4 ratio). Risk of any ISUD diagnosis after first ED diagnosis was estimated by generating hazard ratios (HR). Logistic regression was applied to assess associations between each ED and specific ISUD.
resultsPatients with AN, BN, and USED (without a prior ISUD diagnosis) exhibited an increased relative risk of a subsequent diagnosis of any ISUD compared with respective controls, and the elevated risk persisted over 10 years (AN, adjusted HRs ranging from 1.60 [99% CI 1.15-2.24] to 5.16 [3.14-8.47]; BN, 2.35 [1.46-3.79] to 14.24 [6.88-29.47]; USED, 2.86 [1.35-3.79] to 8.56 [3.31-29.47]). The highest estimates were observed during the first year of follow-up. Each ED type was associated with an increased likelihood of all types of ISUD. AN and USED were most strongly associated with sedatives/hypnotics, BN with other illegal substances (e.g., ecstasy and hallucinogens).
conclusionsED patients have a considerable risk for subsequent ISUD. Prevention efforts and treatment targeting ISUD are likely required to improve ED treatment prognosis.
