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

backgroundThis study aimed to determine how increased muscle mass and athletic performance in adolescence contribute to the prevention of sarcopenia in old age, accounting for the type of sport and the continuation of exercise habits. We compared the prevalence of sarcopenia, its components (low appendicular skeletal muscle mass, low muscle strength, and low physical function), and musculoskeletal pain using data from two cohorts: former athletes who competed in the 1964 Tokyo Olympics and general community-dwelling older adults living in Kashiwa City, Chiba Prefecture.

methodsWe analysed the data from 101 former Olympic athletes (mean age ± SD: 75.0 ± 4.4 years; 26% female) and 1529 general community-dwelling older adults (74.1 ± 5.5 years; 49% women). We assessed sarcopenia (defined by the Asian Working Group for Sarcopenia revised in 2019) and musculoskeletal pain and considered potential confounding factors such as demographic characteristics, for example, sex and exercise habits.

resultsThe prevalence of sarcopenia was significantly lower in former Olympic athletes than general older adults (odds ratios [OR], 0.49; 95% confidence interval [CI], 0.20-0.94), especially with regard to superior appendicular skeletal muscle mass and muscle strength. This effect was more pronounced in individuals who continued their exercise and in athletes whose sporting discipline was classified as having a high exercise intensity. Conversely, low physical function (OR, 2.60; 95% CI, 1.16-6.07) and musculoskeletal pain (OR, 2.22; 95% CI, 1.24-3.97) were more prevalent in former Olympic athletes and in athletes who competed in sports with physical contact.

conclusionsWe observed a lower prevalence of sarcopenia and superior appendicular skeletal muscle mass and strength in the former Olympic athletes, especially among those that continued their exercise habits and those in sports with high exercise intensity. Conversely, low physical function and higher musculoskeletal pain scores were more prevalent in former Olympic athletes, especially among athletes who competed in sports with physical contact. Our results warrant further promotion of exercise in adolescence and beyond as well as providing safety education, which is required to prevent the development of sarcopenia and musculoskeletal pain in old age.
