| Control group | 0(0) | 1(4.2) | 18(75.0) | 5(20.8) | ||
| Week 2 | Intervention group | 13(50.0) | 10(38.5) | 3(11.5) | 0(0) | 0.03 |
| Control group | 4(16.7) | 13(54.2) | 7(29.2) | 0(0) | ||
| Week 4 | Intervention group | 12(46.2) | 8(30.8) | 6(23.1) | 0(0) | 0.006 |
| Control group | 2(8.3) | 8(33.3) | 11(45.8) | 3(12.5) | ||
| Week 6 | Intervention group | 7(36.9) | 14(53.8) | 5(19.2) | 0(0) | <0.001 |
| Control group | 1(4.2) | 8(33.3) | 8(33.3) | 7(29.2) | ||
Notes: Visual analogue scale (VAS) severity was categorized as follows: mild pruritus (VAS<4.0), moderate pruritus (VAS 4.0–7.0), and severe pruritus (VAS>7.0).
