Plant-based diets and the risk of lung cancer: a large prospective cohort study.

ABSTRACT:

Purpose

Plant-based diets are increasingly recognized for cancer prevention, yet their specific impact on lung cancer (LC) risk remains insufficiently examined. This study aims to assess the relationship between plant-based diets adherence and the incidence of LC.

Methods

Data from the Prostate, Lung, Colorectal, and Ovarian cancer screening trial were analyzed. The plant-based diet index (PDI) was developed to assess adherence to plant-based diets. Multivariable Cox regression model was performed to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Restricted cubic spline (RCS) model was performed to examine risk across the PDI spectrum. Prespecified subgroup analyses identified potential modifiers, and sensitivity analyses tested the association's robustness
