Figure 2. Mean Survival Estimates for Time to an Unfavorable Event Among Antituberculosis Therapy Regimens.

The numbers given within parentheses reflect the number of individuals who experienced the event at that particular week after randomization (censored at 24 weeks after randomization). Event-free survival was 22.76 (95% CI, 21.91-23.61) in the daily regimen, 21.34 (95% CI, 20.11-22.57) in the part-daily regimen, and 21.07 (95% CI, 19.91-22.22) in the intermittent regimen, results that were significant according to the log-rank test (P = .03).
