Figure 3

The Bland-Altman Plot presents the difference in estimated BrAC from two breath tests in relation to the mean of the estimated BrAC for the two breath tests (n = 76). The plot indicates no bias and an even distribution of the upper and lower LOAs around 0. The LOAs of 0.34 mg/2 l and −0.37 mg/2 l, indicate differences in the BrAC estimated from two sequential breath tests, and reflect the measurement repeatability.
