Table 2 Medians, minima and maxima for the distribution of WOMAC sub scores for pain, stiffness and daily life activities (range 0 - 100%, 100% = optimum rating) before and four, six, 12 weeks after posterior versus direct lateral approach; p-values derived from two sample Wilcoxon test at each assessment time, respectively

From: Short-term outcome after posterior versus lateral surgical approach for total hip arthroplasty - a randomized clinical trial*
