Values are presented as number (%) or mean±standard deviation. BMI, body mass index; BMD, bone mineral density.
VAS, visual analogue scale.
Dependant variable: existence of anterior thigh pain (patients=1, control=0). OR, odds ratio; CI, confidence interval; BMI, body mass index; BMD, bone mineral density.
Dependent variable: logVAS. Random effect: measuring time. CI, confidence interval; VAS, visual analogue scale.
Values are presented as stem to cortex distance (mm). AP, anteroposterior; Lat, lateral. Distance in 0, 1, and 6 months in patients with thigh pain. Distance in 0, 1, and 6 months in patients without thigh pain.
