Figure 2. The association of Salmonella Typhi lineage and ciprofloxacin susceptibility with treatment failure and fever clearance time in patients randomised to gatifloxacin.
(A) Kaplan-Meier curve for time to treatment failure by H58 and non-H58 Salmonella Typhi. (B) Kaplan-Meier curve for time to treatment failure by Salmonella Typhi susceptibility group (susceptible, intermediate, resistant to ciprofloxacin). (C) Non-parametric maximum likelihood estimators for interval-censored fever clearance time (see methods) by H58 and non-H58 Salmonella Typhi. (D) Non-parametric maximum likelihood estimators for interval-censored fever clearance time by Salmonella Typhi susceptibility group (susceptible, intermediate, resistant to ciprofloxacin).
