Table 2. Comparison of Healing Status and Pain Between the Study Groups at Different Time Points ^{a, b, c}.

	Healing Status (REEDA Scale, 0-15)			Pain (VAS, 0-10)
Group	Baseline	(5 ± 1) d after intervention	(10 ± 1)d after delivery	Baseline	(5 ± 1) d after intervention	(10 ± 1)d after delivery
Horsetail	5.0 ±1.6	2.9 ± 1.4	0.8 ± 1.3	5.7 ± 2.4	4.9±2.4	0.8±1.7
Placebo	4.1 ± 1.6	4.0 ± 1.4	3.5 ± 1.6	5.3 ± 2.2	7.1±2.4	4.6±2.6
Mean difference (95% CI)	0.9 (0.3 to 1.6)	–1.1(–1.7- –0.6)	–2.6 (-3.2- –2.1)	0.4(–0.5-1.3)	–2.3(–3.2- –1.3)	–3.8(–4.7-–3.0)
P Value	0.003 ţ d	P < 0.001	P < 0.001	0.526 ≠ e	P < 0.001	P < 0.001

^aAbbreviations: VAS, visual analogue scale; REEDA, redness edema ecchymosis discharge approximation; CI, confidence interval.

^bData indicate Mean ± Standard Deviation.

^cNumber of participants was 54 in each group at baseline and (5 ± 1) after intervention, and (10 ± 1) after intervention 54 in each group for pain score and 53 in each group for pain score; for REEDA score Mean difference for the baseline comparison and (5 ± 1) after intervention using independent t-test.

^d≠: means whitney

^eţ: Independent t-test.
