Notes: Significantly different in comparison of initial and final test scores of the same group (^*p<0.05). Significantly different in comparison of initial test scores of smoker and non-smoker patients (^‡‡p<0.01, ^‡‡‡p<0.001). Significantly different in comparison of final test scores of smoker and non-smoker patients (^§p<0.05, ^§§p<0.01, ^§§§p<0.001).
