a Nonlinear stance subject data with age and FE load capacity, the dashed line represents the 75th percentile FE load capacity cut-point at 9537N. b Nonlinear fall population data with age and FE load capacity, the dashed line represents the 75th percentile FE load capacity cut-point at 3664N. The 75th percentile is defined from the AGES male fracture cohort. Astronaut data are represented at a single time point to maintain non-identifiable data
