Results of nested case-control study of time-matched participants with and without recurrent parasitemia

Characteristic Cases
n = 9
Controls
n = 9
P value
Age, mos., mean (SD) 27 (16) 34 (17) 0.32
Female gender, n (%) 6 (67) 5 (56) 0.96
Weight, kg, mean (SD) 11.4 (2.6) 12 (2.9) 0.54
Net use, n (%) 9 (100) 9 (100) -
Household indoor residual spraying, n (%) 9 (100) 9 (100) -
Fever on presentation, n (%) 2 (22) 1 (11) 0.66
Anti-malarial use within prior 1 mo., n (%) 2(22) 1 (11) 0.66
Parasite density at enrollment, μL−1, median (IQR) 9,920 (1,640–18,480) 17,040 (3,640–32,360) 0.21
Time to clearance, h, mean (SD) 26 (13) 35 (11) 0.10
Day 7 lumefantrine concentration, ng/ml, mean (SD) 181 (158) 235 (276) 0.64

P values were estimated from chi-squared or Student’s t test. For parasite density at enrollment, the log-transformed data were used for statistical testing.

SD, standard deviation. IQR, interquartile range.
