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
ObjectiveWeekend warrior physical activity (PA) is an emerging pattern associated with health benefits comparable to regular activity. This prospective cohort study investigated the association between weekend warrior PA and all-cause and cardiovascular disease (CVD) mortality in individuals with metabolic dysfunction-associated steatotic liver disease (MASLD), using linked mortality data from NHANES 2007-2018.MethodsPA patterns were classified based on recommended total PA duration (≥150 min/week) and sessions. Weekend warrior PA was defined as achieving this in 1-2 sessions, while regularly active individuals completed ≥3 sessions. MASLD was identified via hepatic steatosis (Fatty Liver Index) and metabolic disturbances.ResultsAmong 10,410 participants with MASLD, meeting recommended PA duration was associated with lower all-cause and CVD mortality versus inactivity. PA frequency inversely correlated with mortality risk up to limited sessions, with no further gains from excess. In fully adjusted models, weekend warrior PA was associated with lower all-cause (HR 0.423, 95% CI 0.233-0.767) and CVD mortality (HR 0.172, 95% CI 0.044-0.677) compared to inactivity. Versus regularly active, it showed no increased risk for all-cause (HR 0.713, 95% CI 0.383-1.329) or CVD mortality (HR 0.261, 95% CI 0.070-1.372). The all-cause mortality benefit was evident only in those aged <60 years.ConclusionsWeekend warrior PA was associated with significantly lower all-cause and CVD mortality in MASLD patients, offering benefits comparable to regular PA, particularly for those under 60. This supports it as a practical option associated with lower mortality.
