Note: mCHEI-2016, modified Chinese Healthy Eating Index; HEI, Healthy Eating Index.
Model 1: Adjusted for age, gender, county, total energy intake.
Model 2: Adjusted for model 1 in addition to tobacco smoking (yes vs. no), pack year of smoking, H. pylori infection status, family history of stomach cancer, body mass index (continuous), education level, and income ten years ago, except for the corresponding variables used for stratification.
