Variable Ulceration (n = 36) No ulceration (n = 540) Magnitude of difference p
Diabetes duration (years) 18.6 ± 12.5 11.6 ± 9.7 Cohen's d = 0.7 MD 7.0 (2.7 to 11.3) 0.002*
Age (years) 64.8 ± 11.4 71.7 ± 11.5 Cohen's d = 0.6 MD -6.9 (-2.9 to -10.8) 0.001*
Past foot pathology (%) Yes: 20.0 No: 2.2 Yes: 80.0 No: 97.8 Cramer's V = 0.3 OR 10.9 (5.1 to 23.3) < 0.001*
