Table 4 **Incidence rate* per treatment arm according to discontinuous or continuous risk intervals analysis**

Model	AL	AS + AQ	AS + SP
Model	IR [95% CI]	IR [95% CI]	IR [95% CI]
Discontinuous time risk intervals	2.01 [1.86-2.17]	1.52 [1.39-1.66]	1.50 [1.37-1.64]
Continuous time risk intervals	1.87 [1.73-2.02]	1.44 [1.32-1.57]	1.42 [1.30-1.55]
p-value	0.09	0.19	0.19

*Malaria episodes/person/year.
IR: Incidence rate; CI: Confidence interval for IR; p-values: Exact mid p-values for risk difference between discontinuous and continuous risk intervals.
