Obesity as a risk factor for multimorbidity: a 23-years population-based prospective study.
Article in Journal of multimorbidity and comorbidity. 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
Background: Obesity and multimorbidity are increasing challenges for public health. While obesity is a well-recognized risk factor for multimorbidity, evidence commonly comes from cross-sectional studies using body mass index (BMI). Evidence on the body roundness index (BRI), a novel indicator of central obesity, remains limited. Objectives: This study assessed midlife obesity as a risk factor for multimorbidity in a Finnish population cohort during 23 years of follow-up. Methods: A total of 1007 participants born between 1933 and 1956 and living in the Savitaipale municipality were enrolled between 1994 and 1996. Baseline data were collected using questionnaires and clinical examinations. Information on 38 chronic diseases was obtained from health registers. Obesity was assessed using BMI, waist circumference (WC), and BRI. Cox proportional hazards models estimated associations with incident multimorbidity, and receiver operating characteristic (ROC) analysis was used to derive BMI, WC and BRI thresholds with the best sensitivity-specificity balance. Results: Over 23 years, obesity defined by BMI and WC, as well as higher BRI, was associated with increased multimorbidity risk. Hazard ratios ranged from 1.52 (95% CI: 1.21-1.92) to 2.17 (95% CI: 1.59-2.97) in women and from 2.41 (95% CI: 1.82-3.19) to 2.79 (95% CI: 2.00-3.90) in men, depending on obesity and multimorbidity definitions. ROC-derived thresholds for multimorbidity prediction were: BMI 26.4 in women and 26.1 in men; WC 76.3 cm and 93.3 cm; and BRI 3.41 and 3.70, respectively. Conclusion: This 23-year study highlights midlife obesity as a risk factor for multimorbidity in later life.
