Pruritus assessment using VAS and 5-D scores at baseline and study end in both groups

	Sertraline group (n = 30)				Placebo group (n = 30)				Comparison between groups
	Baseline	Week 8	p0	Change (Δ)	Baseline	Week 8	p0	Change (Δ)	p1	p2	p3
VAS score (cm)	5.27 ± 2.75	3.45 ± 2.03	< 0.001	↓1.82	4.57 ± 1.94	4.36 ± 2.34	0.469	↓0.21	0.435	0.175	0.002
5D itch scale (point)	17.13 ± 6.99	12.45 ± 3.78	< 0.001	↓4.68	14.93 ± 4.31	15.50 ± 4.81	0.584	↑0.57	0.410	0.009	< 0.001

Data were expressed in Mean ± SD

p₀: p value for comparing between Baseline and Week 8 in each group

p₁: p value for comparing between sertraline group and Placebo group at Baseline

p₂: p value for comparing between sertraline group and Placebo group at Week 8

p₃: p value for comparing the change (Δ) between sertraline group and Placebo group

VAS: visual analogue scale
