  1. M ± SD: Mean ± SD, was used for Analysis of variance test
  2. Median (IQR): Median (Interquartile Range) was used for Kruskal–Wallis test,
  3. ¥Analysis of variance
  4. ¥¥Kruskal–Wallis test, (Significance level P < 0.05)
  5. The mean post-intervention self-efficacy score of the smartphone app group was meaningfully higher than those of the lecture (P = 0.003) and control groups (P = 0.001), according to paired comparisons with Bonferroni correction used to track the differences between the three groups. Nonetheless, the mean post-intervention self-efficacy scores between lecture group and control group were not significantly different (P > 0.05)
