All G1 and G2 combined; all parameters are measured within the IF VOI, i.e. intra-fascia region, excluding the femur, FF_MT fat fraction of muscle tissue derived in Dixon 6pt scans by thresholding muscle and adipose tissue inside the fascia lata, Volume_total volume of IF derived in T₁w data, Volume_IMAT intermuscular adipose tissue volume derived in T₁w data, RMS-SD root mean square of the standard deviation in units of the measured variable, RMS-CV root mean square coefficient of variation in %
