Similarly, agriculture occupation (OR, 1.3; 95% CI: 1.0–1.6; p = 0.033), diabetic foot (OR, 2.0; 95% CI: 1.4–2.8; p < 0.001), PVA > 0.3 (OR, 2; 95% CI: 1.7–2.3; p < 0.001), duration of diabetes (OR, 1.7; 95% CI: 1.6–1.8; p < 0.001), OHA compared with diet (OR, 4.9; 95% CI: 3.2–7.5; p < 0.001), insulin compared with diet (OR, 6.0; 95% CI: 3.6–10.1; p < 0.001) and both (OHA and insulin) compared with diet (OR, 10.9; 95% CI: 6.7–17.8; p < 0.001) were significantly associated with VTDR. Here, INS is linked to diabetes mellitus.
