^a Data from 463 individuals were analyzed

^b OR, odds ratio

^c CI, confidence interval

^d IRR, incidence rate ratio

^e HR, hazard ratio

^f Individuals were divided into two subgroups based on their PfLP levels (more than 75 percentile of whole population or not)

^g Individuals were divided into two subgroups based on their Pf positivity at baseline (Jun-V1)
