Association of MQI.total with the prevalence of CVD, all-cause mortality, and CVD-related mortality among US population, NHANES, 2011–2014. Model 1 was analyzed without covariate adjusted; Model 2 adjusted with physical activity, Model 3 adjusted with sex, age, ethnicity, and physical activity; Model 4 was further adjusted with hypertension, diabetes, smoking status, alcohol use, educational level, PIR, and BMI, and daily sitting time. CVD, cardiovascular disease. CVD, cardiovascular disease. MQI.total, whole-body muscle quality index. BMI, body mass index. PIR, poverty-income ratio. CI, confidence interval
