Table 2.
Distribution of treatment failures and losses to follow-up by year of study.
| (a) by year | 2000 | 2001 | 2002 | 2003 | 2004 | 2005 | 2000–05 |
| KM estimate of success (95%CI) | 96.7 (93.2–98.4) | 94 (90.6–96.2) | 95.7 (90.0–98.2) | 94.9 (88.2–97.8) | 88.5 (79.0–93.8) | 95.9 (91.1–98.1) | 94.6 (93.0–95.9) |
| LTF withdrawn due to AE lost to follow up | 7 | 17 | 2 | 4 | 5 | 1 | 36 |
| 0 | 0 | 0 | 0 | 4 | 5 | 9 | |
| 2 | 1 | 3 | 2 | 1 | 23 | 32 | |
Treatment failures were late parasitological failures [LTF] and withdrawals in the Kaplan-Meier analysis. Losses to follow-up were censored in the KM analysis. See KM analysis in figure 3.
