Table 4 Adjusted odds ratios (aORs) for associations between patterns of JSN and progression

From: Racial differences in associations between baseline patterns of radiographic osteoarthritis and multiple definitions of progression of hip osteoarthritis: the Johnston County Osteoarthritis Project

  1. All models were adjusted for age, gender, race, prior hip injury, body mass index, education, smoking and follow-up time; the progression of radiographic osteoarthritis (rOA) outcome was additionally adjusted for baseline Kellgren–Lawrence grade, while the disability outcome was also adjusted for the Center for Epidemiologic Studies Depression Scale. aStatistically significant after Bonferroni adjustment of p values. bSignificant interaction (p = 0.037) by race: for African Americans the aOR = 1.71, 95 % CI (1.06, 2.74), for Caucasians the aOR = 0.92, 95 % CI (0.68, 1.23).
