Notes:1.β coefficients represent the change in outcome per unit change in the predictor variable.2.P values < 0.001 indicate strong statistical significance.3.Reference categories were selected based on clinical relevance.4.Model 1 and Model 2 represent two independent analytical approaches to validate the findings.5.Variables with no significant association in both models were excluded from the table.
