Fig. 5From: Flexible modelling of risk factors on the incidence of pneumonia in young children in South Africa using piece-wise exponential additive mixed modellingCumulative incidence of pneumonia over the age of children under 2 years by several risk factors estimated by univariable piece-wise exponential additive mixed models. For each variable we chose the time-constant model except for HIV exposure status and weight-for-length at birth where we had sufficient evidence for a time-varying effect. The shaded areas indicate the 95% confidence intervalsBack to article page
