Occupational physical behaviors and knee pain among eldercare workers: A prospective accelerometer study.
Article in Scandinavian journal of work, environment & health, 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
objectiveThe aim of this study was to explore the prospective association between compositions of accelerometry-measured occupational physical behaviors and the risk of knee pain among eldercare workers.
methodsWe performed a prospective study among 377 eldercare workers employed across 20 Danish nursing homes. Occupational physical behaviors were measured using thigh-worn accelerometers over 1-4 working days. Workers reported intensity of and days with knee pain in a questionnaire at baseline and after one year. We explored associations between compositions of occupational physical behaviors [ie, sedentary, standing, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA)] and knee pain, adjusting for potential confounders.
resultsNo significant associations were found. Trends were found for increased occupational time spent in MVPA and decreased risk of days with knee pain [relative risk (RR) 0.58, 95% confidence interval (CI) 0.32-1.05, P=0.07] in main analyses, and for decreased risk of knee pain intensity among non-knee pain cases (RR 0.36, 95% CI 0.12-1.13, P=0.08) in sensitivity analyses.
conclusionsNo significant associations were found between baseline occupational physical behaviors and knee pain at one-year follow-up. However, a non-significant trend suggested that increasing occupational MVPA might be associated with reduced risk of knee pain at follow-up, though studies with larger samples are needed to confirm this finding.
