Pain characteristics and psychological factors that mediate the association between obesity and outcomes of interdisciplinary pain rehabilitation: a registry-based cohort study.
Article in Annals of medicine, 2025. 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
backgroundObesity is a common comorbidity with chronic pain and is closely related to functional and psychological complications of pain, which are also the main outcomes of interdisciplinary pain rehabilitation programmes (IPRP). How obesity influences IPRP outcomes is poorly understood. This study aims to investigate the role of pain characteristics and psychological factors before IPRP as mediators of the association between obesity and IPRP outcomes (i.e. pain intensity and psychological functioning).
methodsSociodemographic variables, pain characteristics and psychological factors were retrieved from the Swedish Quality Registry for Pain Rehabilitation (SQRP). Data at baseline (pre-IPRP) and 1-year follow-up (FU-IPRP) were used in mediation analysis.
resultsOf the 872 patients (mean age 45.8 ± 10.5 years, 80.3% female), 232 (26.6%) were obese (body mass index [BMI] ≥ 30 kg/m
conclusionAt FU-IPRP, patients with obesity experienced improvements in pain and psychological well-being, which were mediated by pain intensity, pain radiation, and depression. The roles of these mediators need to be specifically addressed when designing a tailored IPRP for pain patients with comorbid obesity.
