GPT and metabolic dysfunction-associated steatotic liver disease: Logistic regression analysis highlighted WBC/MPV as a significant predictor of NAFLD in OSAHS populations with the highest odds ratio (OR) after adjustment, reaching 7.559 (95% CI: 1.411–40.486, P = 0.018), followed by gender (OR: 3.672; 95% CI: 1.231–10.954, P = 0.020), BMI (OR: 1.191; 95% CI: 1.028–1.380, P = 0.020), MaSO2 (OR: 1.134; 95% CI: 1.011–1.272, P = 0.031), ALT (OR: 1.049; 95% CI: 1.017–1.083, P = 0.003), HDL-C (OR: 0.070; 95% CI: 0.013–0.396, P = 0.0003), and PLR (OR: 0.980; 95% CI:0.970–0.991, P < 0.001)(Table 4).
