Table 2 Prevalence of structural deformities in the civilian group, military veteran group, and all patients combined, reported as [n (%)], and the P-value for Fisher’s exact tests comparing the proportion of patients in the civilian and military veteran groups

From: Femoroacetabular impingement is more common in military veterans with end-stage hip osteoarthritis than civilian patients: a retrospective case control study
