Note. R = coefficient of determination; F = Fisher-Snedecor test; β = Regression coefficient; t = Student’s t-test; a = Monthly personal income; b = Monthly personal income, whether adverse drug events have occurred; c = Monthly personal income, whether adverse drug events have occurred, taking medicine times a day; d = Monthly personal income, whether adverse drug events have occurred, taking medicine times a day, the number of chronic diseases; e = Monthly personal income, whether adverse drug events have occurred, taking medicine times a day, the number of chronic diseases, sex. Correlation is significant at the 0.05 level
