BMI, body mass index; H2RAs, histamine H2-receptor antagonists; NSAIDs, non-steroidal anti-inflammatory drugs; PPIs, proton pump inhibitors. Multiple regression analysis was performed focusing on the 20 background factors, comprised of two continuous variables (age and BMI) and other 18 categorical variables. The level of significance in each factor was set at P-value < 0.05 (*). All the 20 background factors were sorted in order of absolute values of standardized regression coefficients. Eight lifestyle-related factors are denoted with (†).
