ResultsTwo-hundred and three patients completed the study; 103 were in the intervention group and 100 in the control group. The knowledge improvement between baseline score and follow-up score was greater in the intervention group (mean = 2.835 ± 1.329) compared to the control group (mean = 0.530 ± 0.784) with mean differences = −2.30495, P < 0.001.
