Malaria incidence rates and anti-P. falciparum lysate IgG levels I. Panel A and B, correlation between the mean of anti-P. falciparum lysate IgG levels and malaria incidence rates in the placebo arm. A, stratified by month of birth (red diamonds and lines [linear regression, R² 0.54, p < 0.006], children from the SP arm; blue circles and lines [linear regression R² 0.05, p = 0.475], children from the placebo arm. B, stratified by village of residence (red diamonds and lines [linear regression, R² 0.90, p < 0.001], children from the SP arm; blue circles and lines [linear regression, R² 0.89, p < 0.001], children from the placebo arm). Panel C and D, correlation between malaria incidence rates and incidence rates in the placebo arm. C, stratified by month of birth (red diamonds and lines [slope 0.07, p < 0.80], children from the SP arm; blue circles and lines, children from the placebo arm as comparison [slope 1]). D, stratified by village of residence (red diamonds and lines [slope 0.67, p < 0.007], children from the SP arm; blue circles and lines, children from the placebo arm as comparison [slope 1]). PYAR, person year at risk.
