Table IV.

Patients grouped by presence or absence of FI of the abductors, and subsequent comparisons made using unpaired t-tests for the following variables: age, BMI, TFL:sartorius muscle belly area ratio calculated at the center and inferior aspect of the femoral head, and TFL:sartorius volume ratio

TFL:sartorius area ratio at center of femoral head	2.08 ± 0.54	2.83 ± 1.19	0.004
TFL:sartorius area ratio at inferior of femoral head	2.17 ± 0.54	3.01 ± 1.17	0.001
TFL:sartorius volume ratio	2.10 ± 0.46	2.90 ± 1.07	<0.001
