a

Diagnosis: CM1, sequestration only; CM2, sequestration and fibrin deposition; CM3, coma with no malarial pathology in brain; CM6, severe malarial anemia; CM9, pneumonia and incidental parasitemia.

b

% PV is the percentage of parasitized cerebral microvessels in autopsy tissue sections used for diagnosis of CM (40).

c

Two hundred microvessels from each patient were scored for the presence of thrombin, sequestration (IRBC), neither, or both.

d

Cells with 0 counts made the odds ratio (OR) for those samples impossible to calculate. Estimated OR (eOR) were computed by adding 1 to all cells with a 0 count.

e

Boldface P values are <0.05.
