Lifestyle and body composition changes in patients with rheumatoid arthritis during the COVID-19 pandemic: A retrospective, observational study.

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
Objectives: Behavioral restrictions and staying at home during the COVID-19 pandemic have affected lifestyles. It was hypothesized that patients with rheumatoid arthritis (RA) decreased their activities of daily living (ADL) and exercise during the pandemic. The aim of this study is to investigate the changes in lifestyle and body composition. Methods: Data were obtained from an observational study (CHIKARA study). Of 100 RA patients, 70 (57 women, 13 men) were followed-up with measurements of grip strength, as well as muscle mass, fat mass, and basal metabolic rate by a body composition analyzer. Changes in ADL and exercise were evaluated using a visual analog scale. The relationships between changes in ADL or exercise and body composition were investigated. Results: Muscle mass and grip strength were significantly lower after behavioral restrictions compared to the periods before restrictions (34.0 vs 34.7 kg, P < 0.001; 16.2 vs 17.2 kg, P = 0.013, respectively). Fat mass was significantly greater after behavioral restrictions compared to the periods before restrictions (16.2 vs 15.5 kg, P = 0.014). The mean decrease in ADL was 44%, whereas that of exercise was 20%.The change in muscle mass ( Conclusions: Muscle mass and grip strength decreased and fat mass increased in RA patients with the behavioral restrictions of the COVID-19 pandemic. Muscle mass decreased in patients without exercise. Maintenance of muscle mass may be important during the COVID-19 pandemic.
