*G/L, Giga/L; LDH, lactate dehydrogenase; PADH, postartesunate delayed-onset hemolysis.
†Non-PADH pattern was defined by a hemoglobin nadir and a hemolysis peak occurring before day 8, with or without positive markers of hemolysis after day 8 and without a nadir or sudden drop of hemoglobin after day 8.
‡Median drop in hemoglobin during the first week of treatment was 2.1 g/dL.
§PADH pattern was defined by 1) a new drop in the hemoglobin level after day 8 of treatment initiation and the appearance or reappearance of hemolytic markers (defined as >10% drop in hemoglobin or >10% rise in LDH levels) occurring any time between day 8 and the end of follow-up and/or 2) by any information in the medical chart referring to acute hemolysis occurring after day 8.
¶Median drop in hemoglobin during the first week of treatment was 2.4 g/dL.
