From: Influence of condensation temperature on selected exhaled breath parameters
Concentration (a) and absolute amount (b) of EBC H 2 O 2 at different cooling temperatures. The horizontal grey lines indicate geometric mean (a) and mean values (b). The parameters of the distributions (geometric mean [geometric SD] and mean ± SD for a and b respectively) at different temperatures and the significant differences are also reported. * = p < 0.05; ** = p < 0.01.
