Sex-Specific Differences in Ultrasound-Derived Muscle Parameters and Their Associations with Strength and Physical Function in Older Adults: A Systematic Review and Meta-Analysis.

ABSTRACT:

Introduction

Ultrasound technology is a promising tool for assessing muscle condition in older adults. However, sex-specific differences in how ultrasound-derived muscle parameters related to the physical function remain unclear.

Methods

A systematic search of PubMed, Web of Science, Embase, CINAHL, and SPORTDiscus was conducted to identify studies reporting sex-stratified associations between ultrasound-derived muscle parameters and functional measures. Correlation coefficients were transformed using Fisher's z-transformation and analyzed with random-effects models, then back-transformed to Pearson's r. Heterogeneity was assessed using the I2 statistic, and publication bias was evaluated using funnel plots and Egger's test.
