Correlation between CT density and adjusted CT density of the gluteus medius and muscle strength of the hip abductor. a CT density and adjusted CT density were significantly correlated (r2 = 0.73, p < 0.05). b and c CT density and adjusted CT density positively correlated with hip abductor strength (r2 = 0.30, p < 0.05 and r2 = 0.35, p < 0.05, respectively)
