Falciparum cohort, who withdrew consent after receiving one dose of KAE609. Resolution of Parasite and Fever Clearance Clinical and parasitologic responses are presented in Table 1Desk 1Parasite Clearance in Cohorts of Sufferers with Plasmodium vivax or P. Falciparum Illness. The median times for the resolution of fever were 8 hours in the P. Vivax cohort and 12 hours in the P. Falciparum cohort. The median parasite clearance time was 12 hours in each cohort .Confidence intervals for rate ratios for incidence and mortality were calculated by using asymptotic methods, assuming a standard distribution to get the logarithm of the ratio and a Poisson distribution for the true number of events.18 From the initiation of the trial, an independent data and security monitoring board considered reviews six months and reviewed the accumulating data every. In November 2008, the board unanimously recommended that the current results on prostate-cancer mortality be reported, after notification of study subjects and investigators, on the basis of data showing a continuing lack of a big change in the death rate between your two study groupings at 10 years and information suggesting harm from screening.
