From: The multivariate physical activity signature associated with metabolic health in children
The multivariate PA signature associated different risk factors in children displayed as a selectivity ratio (SR) plot. The models (PLS regression) is adjusted for age and sex. WC:height ratio = waist circumference to height ratio (3 components, R2 = 13.6%); TG = triglyceride (1 component, R2 = 2.2%); TC:HDL ratio = total to high-density lipoprotein cholesterol ratio (1 component, R2 = 3.1%); HOMA = homeostasis model assessment (2 components, R2 = 6.6%); Andersen test (3 components, R2 = 21.0%). The SR for each variable is calculated as the ratio of explained to residual variance on the predictive (target projected) component. A negative bar implies that increased PA are associated with better metabolic health
