CAT and type 2 diabetes mellitus: Notably, an increase in WHR (adjusted odds ratio [AOR] = 70.35; 95% CI = 10.04–493.1, p‐value < 0.001) and elevated AIP (AOR = 4.55; 95% CI = 1.48–13.95, p‐value = 0.008) levels were significantly associated with a higher risk of type 2 diabetes, while higher catalase levels (AOR = 0.33; 95% CI = 0.22–0.49, p < 0.001) correlated with a decreased risk.
