Association between accelerated knee osteoarthritis (AKOA) and risk factors at Osteoarthritis Initiative (OAI) Baseline

Risk Factor at OAI Baseline No KOA (n = 832) AKOA (n = 72) AKOA vs No KOA OR (95% CI)
Body Mass Index (kg/m2) 26.7 (4.3) 30.1 (4.7) 1.16 (1.10, 1.22)
Systolic Blood Pressure (mmHg) 120.2 (15.5) 123.6 (15.4) 1.01 (1.00, 1.03)
Comorbidity Score > 0 (dichotomous) 155 (18.9%) 21 (29.6%) 1.81 (1.05, 3.09)
OTC NSAID Use (dichotomous) 124 (14.9%) 17 (23.6%) 1.77 (0.99, 3.14)
Injury in the next 4 years (dichotomous) 93 (11.7%) 7 (10.1%) 0.85 (0.38, 1.91)

KOA = knee osteoarthritis, OR = odds ratio, 95% CI = 95% confidence interval. All analyses are unadjusted. Bold = statistically significant odds ratio.
