Genetically determined physical activity levels, sedentary behaviours, and their association with the risk of age-related macular degeneration.

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
objectiveTo investigate the causal effects of physical activity and sedentary traits on risk of Age-related macular degeneration (AMD).
methodsA two-sample Mendelian randomization (MR) analysis was used to investigate the causal relationship between physical activity and risk of AMD. We used genome-wide association studies (GWAS) summary statistics from two publicly available biobank-scale cohorts: UK Biobank and FinnGen. Physical activity data were self-reported by 703,901 UK Biobank participants and sedentary behaviour data were gathered from 159,606 FinnGen participants. Our analysis primarily used the inverse variance weighted (IVW) method.
resultEngaging in moderate-to-vigorous physical activity significantly reduced the risk of AMD with an odds ratio of 0.77 (95% CI: 0.66-0.89). However, leisure screen time showed a slight but non-statistically significant upward trend. Sedentary behaviour at work, sedentary commuting showed no causal effects on AMD risk.
conclusionsThis study used MR analysis to examine the causal relationship between physical activity, sedentary behaviour, and AMD. It offers genetic evidence suggesting that physical activity may protect against AMD, emphasizing the significance of lifestyle factors in maintaining ocular health.
