Replacement of leisure-time sedentary behavior with various physical activities and the risk of osteopenia and osteoporosis: evidence from the UK Biobank.

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
Objective: Associations between sedentary behavior (SB) during leisure time and the risk of osteopenia and osteoporosis are inconclusive. We aimed to examine the impact of replacing sedentary time with equivalent durations of various physical activities on the risk of developing osteoporosis. Methods: This is a sub-study from the UK Biobank, in which heel bone mineral density (BMD) was measured via ultrasound densitometry among 193,600 participants. A Logistic regression model and an isotemporal substitution model were used in the analyses. Results: In this study, 52,430 osteopenia cases were recorded, of which 2443 were defined as osteoporosis. In comparison to participants with leisure-time SB < 5 h/day, the odds ratio (OR) of osteoporosis risk was 1.38 (95 % confidence interval [CI): 1.17-1.62) for >8 h/day. Replacing 30 min/day of leisure sedentary time with an equal time spent in the walk for pleasure was associated with a 3 % decrease of osteopenia risk and an 8 % decrease of osteoporosis risk, and replacing 3 min of leisure-time SB with an equal amount of strenuous sports was significantly associated with a 4 % reduction in the risk of osteoporosis and osteopenia (OR = 0.96, 95 %CI: 0.93-0.98 and OR = 0.96, 95 %CI: 0.96-0.97). Furthermore, strenuous sports as an alternative to SBs was significantly associated with a lower risk of osteopenia and osteoporosis, especially in participants achieving 1.5-2.5 h of summer light hours. Conclusion: Leisure-time SB was positively associated with the risk of osteopenia and osteoporosis. Replacing sedentary time with equal time of PA and achieving 1.5-2.5 h of summer sun exposure could be an effective way to reduce osteopenia and osteoporosis burden.
