Dietary patterns and the progression from obesity to sarcopenic obesity in older adults: a prospective cohort study.
Article in BMC geriatrics, 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
backgroundEvidence on dietary patterns and incident sarcopenic obesity (SO) remains limited, and whether associations vary by baseline body composition status is unclear. This study aimed to investigate associations between dietary patterns and incident SO and examine potential effect modification by baseline status (normal, obesity only, or sarcopenia only).
methodsThis study included 3,398 community-dwelling Chinese older adults free of SO at baseline. Dietary data was assessed using a 280-item validated quantitative food frequency questionnaire (FFQ); a priori dietary indices (Diet Quality Index-International [DQI-I], Mediterranean-DASH Intervention for Neurodegenerative Delay [MIND], Okinawa diet score, and Dietary Inflammatory Index [DII]) were calculated, and a posteriori dietary patterns were derived using factor analysis. SO was defined as the coexistence of sarcopenia (Asian Working Group for Sarcopenia 2025 criteria) and obesity (based on body fat percentage). Cox proportional hazards models were used to estimate hazard ratios (HRs) for incident SO.
resultsDuring four years of follow-up, 266 participants developed SO, with approximately 80% of incident cases occurring among participants with baseline obesity. Higher DQI-I (HR 0.854, 95% CI 0.756-0.964 per SD increase), MIND (HR 0.853, 95% CI 0.754-0.965), and Okinawa (HR 0.866, 95% CI 0.764-0.982) scores were associated with a lower risk of incident SO, whereas higher DII scores increased incident SO risk (HR 1.158, 95% CI 1.007-1.332). In stratified analyses, associations for antioxidant-rich (higher MIND and Okinawa scores) and pro-inflammatory (higher DII) diets were significant only among participants with baseline obesity, with no significant associations in those with normal body composition or sarcopenia only.
conclusionsAdherence to dietary patterns with low inflammatory potential and high antioxidant capacity may mitigate the progression from obesity to SO in older adults.
