Reducing misclassification bias in severe malaria research
Abstract
By incorporating platelets and PfHRP2 into standard case definitions of severe falciparum malaria, Watson et al.1 increased diagnostic specificity to 93%. The approach trades off sensitivity and might introduce a selection bias but offers a helpful way to handle misclassification.
