Figure

Percentage of Salmonella isolates with reduced ciprofloxacin susceptibility (MIC >0.125 µg/mL) of domestic (Finnish) origin (A), from Finnish travelers (B), and from Finnish travelers returning from Thailand (C), according to year. Bars represent observed percentages; the continuous curve represents the predicted trend of logistic model for the percentages; the dashed curves are 95% confidence intervals for the predictions.
