Dialysis-imposed, weekly and seasonal patterns of physical activity: a multi-center prospective study in patients using a wearable activity tracker.
Article in Clinical kidney journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Hemodialysis patients are often sedentary, and their life is structured around the dialysis schedule. Wearable activity trackers present an opportunity for long-term continuous monitoring of physical activity. We aimed to characterize dialysis-imposed, weekly and seasonal patterns of physical activity in hemodialysis patients. Methods: In this prospective observational study, patients on in-center hemodialysis in New York City wore the Fitbit Results: A total of 109 patients on hemodialysis were included (mean age 54 ± 11.6 years, 72% male, 23% diabetic). The observed number of steps was 6590 ± 4014 (mean ± standard deviation) per day; 44 (40%) participants walked <5000 steps/day. Participants walked 912 (95% confidence interval 768, 1057) fewer steps on Sundays and 284 (129, 440) fewer on the second interdialytic day vs dialysis day. Winter activity was reduced by 321 (162, 478) to 455 (312, 598) steps compared with other seasons. Older age, diabetes and higher equilibrated Kt/V were associated with lower physical activity levels; higher albumin was associated with increased physical activity levels. Conclusion: Most hemodialysis patients walked less than recommended level of 10 000 steps/day and physical activity levels vary greatly between and within patients. Dialysis-imposed, weekly and seasonal patterns affect physical activity. Lower physical activity levels on second interdialytic days and Sundays could provide opportunities for improvements of physical activity in shared the decision-making process.
