*
For differences in means/proportions across all 3 treatment arms.
†
Difference in mean/proportion with 95% CI for that difference.
‡
Cells to small for valid interval estimation using normal approximation and for chi-square P value deaths in the field, field or ED, and within 6 hours are cumulative; percentages are computed on the basis of total number treated on each arm.
