(A and B) Risk of frailty by Fried frailty phenotype (FFP) (A) and short physical performance battery (SPPB) (B) by appendicular skeletal muscle mass index (ASMI). Generalized additive models; horizontal dark dotted black line represents the effect estimates. Surrounding thin lines represent 95% confidence bands. Full-height solid and dashed vertical lines represent sex-specific ASMI cut-points for sarcopenia diagnosis. Each vertical line in the rug plot along the x-axis represents a single study subject. Models are adjusted for age, sex, and diagnosis.
