Fig. 3From: The duration of protection against clinical malaria provided by the combination of seasonal RTS,S/AS01E vaccination and seasonal malaria chemoprevention versus either intervention given aloneProtective efficacy of RTS,S/AS01E vaccine against clinical malaria, by time since vaccination, in each year of the study, using three methods. Footnotes: Protective efficacy was estimated using three methods by comparing children randomised to receive SMC and either control vaccines (SMC alone group) or RTS,S/AS01E vaccine (combined group). The left panels show results from piecewise Cox regression models. The middle panels show estimates from flexible parametric survival models. The right panels show results from Smoothed Schoenfeld Residuals from Cox regression modelsBack to article page
