Work is associated with a more robust rest-activity rhythm and high-intensity physical activity among older adults.

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
backgroundWork participation is a major element of active aging in aging societies. However, the impact of work on physical activity and rest-activity rhythm has not been well-studied in the older population.
aimsTo investigate the association of work status with the distribution of physical activity and rest-activity rhythm.
methodsThe study recruited 35 working and 72 non-working community-dwelling adults older than 60 years old. Biological rhythm was evaluated by dim light melatonin onset (DLMO). Activity distribution and rest-activity rhythm indicators were derived from 14-day actigraphy data, and differences between working and non-working groups were analyzed. The association of activity distribution and rest-activity rhythm indicators with mood symptom was examined.
resultsCompared to non-working older adults, those who were working exhibited an earlier wake-up time (05:24 h vs. 06:11 h, p = 0.001) and higher levels of daytime activity (most active 10-hour activity count: 25605 vs. 16838, p < 0.001), but similar DLMO (20:20 h vs. 20:24 h, p = 0.914). Work is associated with a more robust rest-activity rhythm as assessed by interdaily stability (β = 0.18, p < 0.001) and autocorrelation coefficients (β = 0.09, p = 0.002). Regarding activity distribution, work is associated with high-intensity activity in shorter bouts, as shown by a lower Gini index (β = -0.04, p = 0.003) and a higher intensity gradient (β = 0.54, p < 0.001).
conclusionsWorking and non-working older adults showed similar biological circadian rhythms, but working ones had a more robust rest-activity rhythm and higher levels and intensity of physical activity.
