Zero-Inflated Models for Identifying Relationships Between Body Mass Index and Gastroesophageal Reflux Symptoms: A Nationwide Population-Based Study in China

This study examined the relationship between body mass index (BMI) and gastroesophageal reflux symptoms in a large population-representative sample from China.
