† Cases: with fever, axillary temperature ≥ 37.5°C at hospital visit.
‡ Controls: without fever, axillary temperature < 37.5°C at hospital visit and no reported history of fever during the preceding 3 days.
¥ Percentage of patients in a certain parasite density class among cases/controls. aOR: odds-ratio (of fever at each stratum of parasite density, versus uninfected patients), adjusted for age; AF: attributable fraction, calculated as: ;
£ (AF by definition ≥ 0)
PrevMal = % febrile patients with malaria infection
PAF: population attributable fraction, calculated as: PAF = AF(PrevMal).
