Diagnostic progression to hoarding disorder: the longitudinal course of hoarding behavior.
Article in BMC psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe longitudinal course of hoarding behavior (HB) in children and adolescents, as well as the predictors of its outcome, remain unknown. This prospective longitudinal study aims to evaluate the four-year course of HB and identify predictors of progression to hoarding disorder (HD) and the persistence of hoarding symptoms.
methodsChildren and adolescents with HB underwent a clinical assessment after a four-year follow-up period. The assessment included a one-on-one psychiatric interview, an HD clinical interview based on DSM-5 diagnostic criteria, Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL), a semi-structured diagnostic interview for comorbid diagnoses, and the Children’s Saving Inventory (CSI) to assess hoarding symptom severity.
resultsOver the 4-year follow-up period, 42.2% (n = 19) of participants progressed to HD, 20% (n = 9) persisted in HB, and 37.8% (n = 17) no longer displayed hoarding symptoms. Baseline hoarding symptom severity significantly predicted progression to HD and was also associated with persistence of hoarding symptoms. In exploratory models, current psychiatric comorbidity and female gender were associated with persistence but not progression.
conclusionsThese findings provide precious insights into the longitudinal course of HB and predictors. The results also suggest the importance of early identification and monitoring of HB.
