Number of ring-stage parasites that develop into late stages. Box plots showing the number of parasites developing from ring- to late-stage parasites, either cellulose-filtered (+) or non-filtered parasites (−) from day 0 to day 5. The lower whisker indicates the lowest data point above Q1 minus 1.5 times IQR, the upper whisker indicates the highest data point below 1.5 IQR plus Q3. Values below Q1 minus 1.5 IQR and above Q3 plus 1.5 IQR are indicated as points. Statistical significance was calculated using Wilcoxon’s signed rank test. *P = 0.02
