Univariable and multivariable cox proportional models of skeletal mass index (SMI) for overall and recurrence free survival. SMI quantified at L4 vertebral levels was categorized using the sex specific median into ‘High’ (red) and ‘Low’ (blue). The survival curves for univariable and multivariable models for overall and recurrence free survival between the high and low SMI groups are shown. Hazard ratios (HR) and Wald p values are shown
