Table 3. Effect of treatment A and B on parasitological cure rate of Schistosoma haematobium-infected children compared with treatment C at 2 weeks after praziquantel treatment.

Treatment groups	Baseline, positive, No.	Post-treatment, % (No.)	RR	95% CI	P value
C	80	83.8a (57/68)	Reference
A	47	87.1 (27/31)	1.03	0.99–1.07	0.12
B	72	82.4 (28/34)	1.00	0.95–1.05	0.98

RR = relative risk, CI = confidence interval.

^aCure rate = (Number of negative children after treatment who were positive at baseline survey/Number of positive children at baseline survey) × 100.
