Association of malaria incidence rate ratios (and 95 % confidence intervals) with CD4 count at time of malaria episode as observed during follow up, modelled using restricted cubic splines with 4 knots in a random effects Poisson regression model, unadjusted (a), and adjusted for covariates during baseline and follow up (b). A CD4 count of 200 was used as the reference to calculate the rate ratios
