Daily physical activity measured by a wearable activity monitoring device in patients with rheumatoid arthritis.
Observational study in Clinical rheumatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
introductionActivities of daily living in patients with rheumatoid arthritis (RA) have been evaluated by patient-reported outcomes. However, it has been difficult to measure activity intensity quantitively. Calories expended, exercise, and steps were measured quantitively by a wearable activity meter, and their associations with patients' background characteristics were examined.
methodsData from a prospective, observational study (CHIKARA study) were used. Eighty-five of 100 RA patients were entered and wore a wearable activity meter for 7 days. The daily calories expended and exercise for both walking and housework and steps were evaluated. Total daily calories expended and exercise was defined as the sum of walking and housework. The relationships of DAS28-ESR, mHAQ, body composition, muscle function, and general status were analyzed.
resultsThe median age was 66.0 years, and the disease duration was 5.3 years. DAS28-ESR was 3.11, and mHAQ was 0.125. Total daily calories expended, exercise, and number of steps were 461.7 kcal, 3.97 METs h, and 4,788, respectively. MHAQ, walking speed, power, locomotive syndrome, and frailty were independently related to exercise. Total daily exercise and steps of the moderate and high disease activity group were significantly lower than those of the remission group. When the number of steps was < 3,333 and < 2,468, the odds ratios for locomotive syndrome and frailty increased 14.4-fold and 8.7-fold, respectively, using Fisher's exact test (P < 0.001).
conclusionsDaily physical activity and number of steps were significantly decreased in RA patients with moderate and high disease activity as measured by a wearable activity meter. Key Points • Total daily calories expended and exercise for both walking and housework and steps in patients with rheumatoid arthritis were 461.7 kcal, 3.97 METs h, and 4,788, respectively, using a wearable activity meter. • Daily physical activity, especially total daily exercise and number of steps, was significantly decreased in RA patients with moderate and high disease activity. • When total daily steps were < 3,333 and < 2,468, the odds ratios for locomotive syndrome and frailty increased 14.4-fold and 8.7-fold, respectively.
