Baseline characteristics of isolates for which the ex vivo assay was accomplished
| Baseline characteristic | P. falciparum | P. vivax |
|---|---|---|
| No. of isolates reaching harvest/total no. of isolates (%) | 23/25 (92) | 18/21 (90) |
| Median (range) delay from venipuncture to start of culture (min) | 140 (80–246) | 102.5 (77–180) |
| Median (range) duration of assay (h) | 46 (32–56) | 47 (41–48) |
| Geometric mean (95% CIa) parasitemia (asexual parasites/μl) | 17,291 (11,212–26,666) | 11,110 (6,925–17,823) |
| Median initial % (range) of parasites at ring stage | 100 (100–100) | 85 (59–97) |
| Mean (95% CI) schizont count at harvest | 36 (16–80) | 34 (20–50) |
