Long-term intensity and volume of biking, swimming, and tennis: Associations with mortality risk in US older men.
Article in Preventive medicine, 2025. 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
objectivesTo study the association of intensity and volume of individual physical activities with mortality risk among US older males.
methodsWe prospectively followed 10,218 men in Health Professionals Follow-up Study (2012-2022) who were free of diabetes, cardiovascular disease or cancer at baseline. Intensity of biking, swimming and tennis was assessed using biennial questionnaires and categorized into two intensity groups: low intensity, medium/high intensity. Cumulative averaged physical activity volume was classified based on tertiles: low volume, medium/high volume. We examined joint associations of physical activity intensity and volume with mortality using multivariable-adjusted Cox proportional hazards regression models to estimate hazard ratios (HRs) and 95 % CI.
resultsDuring 89,168 person-years of follow-up (mean [SD] age at baseline, 73.8 [6.9] years [range, 65-102 years]), 2303 deaths were documented. Medium/high intensity performed at medium/high volume was suggestively associated with reduced mortality risk for biking (HR: 0.83 [95 % CI: 0.73, 0.94]), swimming (HR: 0.81 [95 % CI: 0.63, 1.03]), and tennis (HR: 0.83 [95 % CI: 0.65, 1.05]), compared with non-participation in these activities, respectively. Further, specific levels of intensity and volume in biking (medium/high intensity and low volume: HR 0.89 [95 % CI: 0.76, 1.05]), swimming (low intensity and low volume: HR 0.77 [95 % CI: 0.57, 1.06]), and tennis (low intensity and medium/high volume: HR 0.49 [95 % CI: 0.23, 1.01]) were suggestively associated with reduced mortality risk compared with non-participants.
conclusionsBoth physical activity intensity and volume inform on mortality risk for biking, tennis and swimming, highlighting the necessity of examining both factors in future research.
