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