Follow up of serial urea breath test results in patients after consumption of antibiotics for non-gastric infections

Figure 1 Changes in the delta ¹³C values (△ ¹³C) of urea breath tests after consumption of antibiotics in H. pylori-infected patients. The broad line indicated the duration of antibiotics consumption. A delta ¹³C value of greater than 5 was regarded as a positive result. There was a significant difference between the median delta ¹³C values taken at baseline, one-week and six-week post treatment (P = 0.022). Post-hoc analysis showed that only the difference between the first and the third urea breath tests reached statistical significance (P < 0.05).
