Bolded ROIs indicate primary ROIs per analytic plan. Eta2 (row 1 per ROI) and P‐values (row 2 per ROI) are derived from models that are crude (unadjusted) or adjust for phantom values (column A1), or both phantom and hip DEXA scores (column A2), respectively. P‐levels shown are prior to correction for multiple comparisons; the critical level for Bonferroni corrected significance is P < .003 for secondary ROIs.
