(Top) Kaplan-Meier estimates of the proportion of children with an episode of malaria. (Bottom) Diagram showing the 90% and 95% confidence intervals for the odds ratios for ATP and ITT analyses for the primary endpoint (malaria with parasitemia above 3,000/μl) and for the secondary endpoint (malaria with parasitemia at any density). An odds ratio of 1.64 was specified as the noninferiority margin. The 90% and 95% CIs cross this margin for some analyses but are entirely above 1, so we are confident that SPAQ is superior to DHAPQ and are somewhat less confident in our conclusion that the DHAPQ is not inferior to SPAQ.
