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

backgroundTo establish sex-specific cut-off values for maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) in elderly women, aiming to improve the screening of sarcopenia and to explore their implications for respiratory sarcopenia by accounting for physiological differences in muscle strength and mass.

methodsEighty-eight older women were assessed for respiratory muscle strength (MIP, MEP), hand grip strength (HGS), and skeletal muscle mass index (SMI). Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia consensus criteria (HGS < 18 kg; SMI < 5.7 kg/m²). Pearson correlation coefficients were calculated between respiratory muscle strength and conventional sarcopenia indicators. Receiver operating characteristic (ROC) analysis was conducted to derive optimal cut-off values for MIP and MEP. Sarcopenia prevalence was compared using three threshold strategies: -1 standard deviation (SD) and -2SD from healthy young women, and the 20th percentile from age-matched older adults.

resultsMIP and MEP were significantly correlated with HGS (

conclusionMIP and MEP may serve as accessible and complementary indicators that support the screening of sarcopenia and provide implications for respiratory sarcopenia in elderly women. The use of sex- and age-specific cut-off values could enhance diagnostic precision and facilitate early intervention strategies for respiratory muscle decline in aging populations.
