a

Δ Median denotes change in median which is calculated by (Post-test median – Pre-test median).

b

% has been calculated using (median/maximum score) ×100.

c

Δ % Score denotes change in score which is calculated by (%Post-test median – % Pre-test median).

d

P-value was calculated using Wilcoxon signed-rank test (comparing pre-test median and post-test median scores) since the post-tests were left-skewed.
