All values are represented as counts (weighted percentages). p-value compares the prevalence within each subgroup between Prevalence using GS vs. Prevalence using GS/BMI
FNIH – Foundation for the National Institutes of Health; GS - Grip Strength; GS/BMI – Grip Strength divided by BMI.
Grip Strength cutoffs are <16kg in females and < 26kg in males, and GS/BMI men <1.0; women <0.56. GS/BMI represents grip strength (in kilograms) divided by body mass index.
