In addition, using the chi-square test in the diabetic patient group revealed a significant association between COVID-19 outcomes and serum creatinine levels (p=0.0001), urea (p=0.0001), CPK (p=0.005), and LDH (p=0.019), but no significant association between the outcomes and WBC (p=0.118), ALT (p=0.705), and AST (p=0.123). The gene discussed is PIK3C2A; the disease is COVID-19.
