bResults A–C positive responses to PT
*Significantly associated with the increase in the K rate during PT compared to the K rate before PT (Wilcoxon test; p = 0.005). There was no statistically significant difference (Mann-Whitney U test; p = 0.65) in the K rate during PT between positive responses to PT (Table 1) and inadequate responses to PT (Table 2)
