Effects of a personalized exercise program on physical function in older patients with rheumatoid arthritis at high risk of sarcopenia: results of a randomized controlled trial.
Trial report in Arthritis research & therapy, 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
backgroundPatients with rheumatoid arthritis (RA) are at a higher risk for sarcopenia than the general population. Exercise therapy can improve muscle strength in older adults; however, its efficacy in older patients with RA has not been fully established. This study aimed to evaluate the efficacy of a personalized exercise program on physical function in older patients with RA at high risk for sarcopenia.
methodsA single-centre, parallel-group, two-arm, superiority randomized controlled trial was conducted in patients with RA aged 60-85 years who were at risk of sarcopenia. The intervention group (n = 69) underwent a 16-week personalized exercise program in addition to nutritional guidance and standard care, whereas the control group (n = 65) received only nutritional guidance and standard care. The primary outcome was the change in the total Short Physical Performance Battery (SPPB) scores from baseline to week 16.
resultsA total of 140 patients were randomized. Of these, 134 initiated the assigned intervention. There was a 0.2-point difference in SPPB total score from baseline to week 16 between the intervention group (+ 0.4 points) and the control group (+ 0.2 points); 95% confidence interval: -0.1 to 0.5; p = 0.206. Regarding the secondary outcomes at week 16, there was a tendency for improvement in the chair-stand test, grip strength, and the mental component score.
conclusionThe 16-week personalized exercise therapy did not improve the total SPPB scores. However, the intervention may improve standing ability, grip strength, and mental health-related quality of life in older patients with RA at high risk of sarcopenia.
