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

This study aimed to (1) establish age- and sex-specific functional fitness (FF) norms in Chinese older adults living in urban communities and (2) explore ageing-related degradations and sex differences in each FF dimension. A pool of 2398 individuals (1128 men; 1270 women) aged 60-98 years were recruited from urban communities of Nanjing, China. FF was measured using the Senior Fitness Test battery. FF norms were established for men and women in 5-year age intervals using five percentiles (10th, 25th, 50th, 75th, 90th). Significant degradations in FF were correlated with increases in age. Around half of test items in 75-79 years group (3 for men; 4 for women) and over half in 80-84 years group (5 for men; 4 for women) exhibited significant decreases in FF compared with the adjacent younger group, indicating that ages of 75 and 80 years are two potential turning points in FF declines. Significant differences existed between the overall FF of men and women; women outperformed men in flexibility and men outperformed women in upper body strength, agility/dynamic balance, and aerobic endurance. Significant age and sex effects occurred in each fitness dimension, which helps individualised program design and promotes an active lifestyle in older adults.
