1 · What the graph read from it

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.

2 · The registry

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

aimRegular moderate-to-vigorous physical activity (MVPA) is associated with lower risks of functional decline and disability. Whether concentrating MVPA into 1 or 2 days per week-the "weekend warrior" pattern-is associated with disability risk similarly to regularly distributed activity remains unclear, particularly among individuals with high sedentary behavior.

methodsWe analyzed wrist-worn accelerometer data from 41 225 UK Biobank participants without identifiable baseline disability based on available indicators (mean age 61.6 years; 60.3% women). Participants were classified as inactive (< 150 min/week), weekend warriors (≥ 150 min/week with ≥ 50% accumulated in 1-2 days), or regularly active (≥ 150 min/week but not weekend warriors). Disability was assessed once during follow-up and defined as a self-reported need for assistance with at least one of six activities of daily living because of a health condition. Associations with incident disability were estimated using Cox proportional hazards models for interval-censored outcomes, adjusting for sociodemographic characteristics, lifestyle factors, and baseline health status.

resultsDuring a median follow-up of 7.7 years, 2589 participants were classified as having disability at follow-up. Compared with inactive individuals, weekend warrior and regularly active patterns were associated with similarly lower disability risk (weekend warrior: HR 0.68, 95% CI 0.61-0.75; regularly active: HR 0.66, 95% CI 0.60-0.73). These associations were observed across sedentary behavior levels.

conclusionsAccumulating recommended MVPA within 1 or 2 days per week was associated with disability risk reductions comparable to regularly distributed activity. Flexible activity patterns may help support functional independence and healthy aging.
