Incident infections: comparison of odds of symptomatic malaria between infections harboring new versus recurrent pfcsp haplotypes. A, Multilevel logistic regression results for the odds of symptomatic malaria comparing (1) only new versus only recurrent (black) and (2) new and recurrent versus only recurrent (black) pfcsp haplotypes. Dots indicate the odds ratios and lines the 95% confidence intervals. B, Assessment of effect measure modification on symptomatic disease by age. Adjusted multilevel logistic regression models comparing the odds of developing symptomatic malaria between (1) only new versus only recurrent and (2) new and recurrent versus only recurrent haplotypes were computed conditioned on age category. Dots indicate the odds ratios and lines the corresponding 95% confidence intervals.
