p1 = Between IG and CG at baseline.

p2 = McNemar, (within IG and CG).

p3 = Chi-square for independence (between IG and CG), IG = Intervention group, CG = Control group.

Significant improvement = p < 0.01 marked with bold font. Significant improvement = p < 0.01 because of repeated tests. Effect size measured by Cramer’s V.

% = Percentage of correct answer.
