1 · What the graph read from it

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.

2 · The registry

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

purposeTo investigate the association between best-corrected visual acuity (BCVA) and sarcopenia in older adults, while the relationship between low visual acuity and age-related muscle decline remains unclear. STUDY

designCross-sectional study.

methodsThis cross-sectional study included 874 participants in the Kyotango Longevity Cohort Study from August 2017 to June 2022. We analyzed the association between best-corrected visual acuity (BCVA) and the presence of sarcopenia, grip strength, gait speed, and skeletal muscle index (SMI) in older adults. Logistic regression analyses were performed with sarcopenia as the dependent variable and visual acuity as the independent variable, adjusted for age, sex, body mass index (BMI), HbA1c, smoking, exercise, and alcohol consumption. Decimal BCVA was converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analyses.

resultsThis cross-sectional study comprised 356 men and 518 women, with a median age of 72.0 years (range: 65-98 years). The prevalence of sarcopenia was 6.7% (24 cases) in the men and 5.2% (27 cases) in the women. Multivariate logistic regression analysis revealed a significant association between low visual acuity and sarcopenia for both sexes [odds ratio: 1.86, 95% confidence interval (CI): 1.23-2.81, p = 0.002 for men, and odds ratio: 1.45, 95% CI: 1.01-2.02, p = 0.038 for women).

conclusionsThis study demonstrates a significant relationship between lower visual acuity and sarcopenia. These findings support maintaining visual acuity to prevent age-related decline of physical functions.
