Impact of Physical Activity Frequency, Duration, and Intensity on Senile Cataract Risk: A Mendelian Randomization Study.
Article in Translational vision science & technology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Purpose: We aimed to determine the causal effects of physical activities with different frequencies, durations, and intensities on the risk of senile cataracts using Mendelian randomization (MR). Methods: A bidirectional two-sample MR approach was used to determine the association between physical activity and senile cataract risk. Our primary analysis used the inverse variance weighted method, and secondary analyses included MR-Egger regression, MR-PRESSO, and Cochran's Q statistic to evaluate heterogeneity and pleiotropy. Causal estimates were presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). Results: Genetically predicted moderate physical activity ≥ 10 min/wk (OR = 0.765, 95% CI = 0.627-0.936, P = 8.73E-03), vigorous physical activity ≥ 10 min/wk (OR = 0.691, 95% CI = 0.521-0.917, P = 1.04E-02), moderate-to-vigorous physical activity levels (OR = 0.552, 95% CI = 0.369-0.823, P = 3.75E-03), and overall acceleration average (OR = 0.952, 95% CI = 0.926-0.978, P = 3.80E-04) were associated with a decreased risk of senile cataract while walking ≥ 10 min/wk (OR = 0.972, 95% CI = 0.741-1.275, P = 8.36E-01) had no significant correlation. The reverse MR analysis showed no reversal causality from senile cataract to physical activity except for walking ≥ 10 min/wk (OR = 0.951, 95% CI = 0.923-0.979, P = 7.30E-04). Conclusions: Our findings suggest that moderate to vigorous physical activity with higher frequency and longer duration will causally reduce the risk of senile cataracts, and there is no reverse causal relationship. Translational Relevance: These findings underscore the potential of incorporating physical activity into preventive health strategies for senile cataracts.
