Elevated serum creatinine (OR 6.07, P<0.001) and urea (OR 5.25, P<0.001) were strongly linked to complications, as were hyperbilirubinemia (OR 3.71, P<0.001) and elevated SGOT (OR=2.16, P 0.001), though SGPT and ALP showed weaker associations. The gene discussed is GPT; the disease is Hyperbilirubinemia.
