Note. R = coefficient of determination; F = Fisher-Snedecor test; β = Regression coefficient; t = Student’s t-test; a = Whether adverse drug events have occurred; b = Whether adverse drug events have occurred, the number of chronic diseases; c = Whether adverse drug events have occurred, the number of chronic diseases, education. Correlation is significant at the 0.05 level
