Dietary intake was assessed using a food frequency questionnaire and converted into PDI, hPDI, and uPDI. Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality. The proportional hazards assumption was evaluated using Schoenfeld residuals, and dose-response relationships were examined using restricted cubic splines.\n                    <\/jats:p>\n
