Effect of vitamin D, omega-3 supplementation, or a home exercise program on muscle mass and sarcopenia: DO-HEALTH trial.
Trial report in Journal of the American Geriatrics Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundWe aimed to investigate the effect of daily supplemental vitamin D, omega-3s, and a thrice-weekly home exercise program, alone or in combination, on change of appendicular lean muscle mass index (ALMI) and incident sarcopenia in older adults.
methodsThis is a secondary endpoint analysis of a 3-year randomized, double-blind, placebo-controlled trial with a 2 × 2 × 2 factorial design among 2157 community-dwelling, healthy adults aged 70 + years, from 2012 to 2018 (DO-HEALTH). Participants were randomized to 2000 IU/d vitamin D and/or 1 g/d marine omega-3s and/or exercise. Change in ALMI over 3 years was calculated in all participants who underwent dual energy X-ray absorptiometry (DXA) (n = 1495) using mixed effect models. Incident sarcopenia was analyzed based on the Sarcopenia Definitions and Outcomes Consortium in all non-sarcopenic participants (n = 1940).
resultsAmong 1495 participants (mean age 74.9 (sd 4.4); 63.3% were women; 80.5% were at least moderately physically active at baseline) mean gait speed at baseline was 1.2 m/s (sd 0.3), mean ALMI at baseline was 6.65 (SD 0.95) in women, and 8.01 (SD 0.88) kg/m
conclusionAmong healthy, physically active older adults, ALMI and incidence of sarcopenia were not improved by treatment of daily 2000 IU vitamin D, daily 1 g omega-3s, or a simple home exercise program compared with control over 3 years.
