Fig. 1: Sequencing performance.

A Total number of reads per sample (n = 558) by parasite density before filtering. Red indicates pregnant women at their first ANC visit, and blue indicates children sampled in household surveys. B Number of loci (total n = 224) with reads per sample (n = 558) by parasite density before filtering. C Parasite density among samples that passed and did not pass filtering by population group (n = 378 ANC users and n = 180 children). D, E Reads per locus per included sample (n = 382) for diversity loci by chromosome and for drug resistance markers by gene, respectively. On average, each locus was covered by 1.4 million reads. Boxes indicate the 25th and 75th percentiles with the centre line indicating the median, and the whiskers indicate the smallest value within 1.5 times interquartile range below the 25th percentile, and the largest value within 1.5 times the interquartile range above 75th percentile.
