Pearson correlation coefficients and χ2 statistics of the comparison between the temporal trends in PfPRqPCR (first six rows) and PfPRRDT (last six rows) in different populations of pregnant women at first ANC visit and the mean weekly number of clinical cases, with their time lag of optimal correlation. A time lag of 89 days indicates that the results of the clinical cases in children had the best correlation with the results of pregnant women taken 89 days after the clinical cases in children.
