Figure 5From: 2-Aminoacetophenone as a potential breath biomarker for Pseudomonas aeruginosa in the cystic fibrosis lung A time degradation graph of 2-AA in glass sampling bulbs. The 2-AA levels (mean and SD) from three replicate experiments are shown and a five parameter logistic function fitted to the degradation curve (11.73 hours (95% CI 10.94, 12.52). 2-AA levels at 8 and 10 hours were significantly less (P < 0.001) than four and six hours.Back to article page
