PvLDH (ng/ml)	26.2 (10.7–57.3)	96.6 (85.6–154)	0.012
PvLDH/Log parasitemia	3.06 (1.33–7.73)	10.42 (9.27–18.60)	0.027
pLDH (ng/ml)	44.6 (7.8–142)	308 (258–619)	0.015	50.23 (22.9–121)	86.79 (39.3–452)	0.016
pLDH/Log parasitemia	6.46 (1.60–20.1)	36.7 (27.9–58.3)	0.021	5.54 (2.33–13.13)	7.58 (3.51–65.65)	0.058
HRP2 (ng/ml)				72.8 (32.8–260)	541 (125–1590)	<0.0001
HRP2/Log parasitemia				9.04 (3.38–23.55)	49.0 (13.8–196)	0.0002

Note: Values are median (inter-quartile range).

Ratios are calculated as ngs/1000 peripheral parasites, with the denominator log-transformed to a normal distribution.
