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

Background: Ultrasonography can be used to evaluate the echo intensity (EI) and strain ratio (SR) to identify muscle quality and stiffness, respectively. EI and SR are affected by aging, frailty, and joint angle positions. We investigated the effects of aging and frailty on muscle EI and SR at different joint angle positions, and identified a useful measurement method to reflect muscle changes related to contractures in frail older adults. Methods: This study had a cross-sectional design. Twenty-two healthy young adults (young group), 22 non-frail older adults (non-frail group), and 22 frail older adults (frail group) participated in this study. The range of motion (ROM) of hip abduction, EI, and SR of the adductor longus in the zero- and full-abduction positions were measured. To investigate the effects of aging and frailty, the Kruskal-Wallis test, followed by the post-hoc Steel-Dwass test, was used. In addition, to confirm whether EI and SR in each position were useful for assessing contracture, Spearman's correlation test was used. Results: ROM and SR in full-abduction were significantly lower in the frail group than in the other groups and lower in the non-frail group than in the young group. The SR in full-abduction (ρ = 0.73, Conclusions: SR in full-abduction is affected by both frailty and aging and is useful for evaluating muscle stiffness related to contracture in frail older adults.
