Effects of retinoscopy practice time on the performance rate. A Analysis for differences in the complete group, B Analysis for differences in the Undergraduate group, C Analysis for differences in the Graduate group. For each time (08, 12, 16 and 20 hrs). Data are presented as mean and (± SD), using Mann-Whitney U test or Kruskal-Wallis test. A p-value less than 0.05 was considered statistically significant. Significance is indicated by the following symbols: * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.00001, ns = not significant. Post hoc analyses were applied (Dunn's test, p < 0.05)
