Notably, the positive association between the ALT/AST ratio and OSA risk appeared to be more pronounced in females (OR, 1.63; 95% CI, 1.13–2.35) than in males (OR, 1.31; 95% CI, 0.91–1.88), although the test for interaction was not statistically significant (P for interaction = .565). The gene discussed is GPT; the disease is obstructive sleep apnea syndrome.
