FIGURE 2.

Distribution of trough and peak PT values of the 15 mg group and the 30 mg group. The PT values showed no significant difference between the two groups for both trough and peak values. However, there was a trend of lower peak values observed in the 15 mg group. Horizontal line in boxes represents medians. Tops and bottoms of boxes indicate 75th and 25th percentile, respectively. Tops and bottoms of bars indicate maximum and minimum non‐outliers, respectively. Circles indicate outliers above or below 1.5 times interquartile range from the 75th and 25th percentiles. The PT values were evaluated in the part of the patients (in the 15 mg group, 16 of 19 patients, and in the 30 mg group, 27 of 49 patients) by the discretion of the attending physician.
