Table 2.
Metabolites’ concentrations (mmol/L), expressed as mean ± standard deviation, quantified by 1H-NMR in exhaled breath condensate (EBC) samples of control group (Group C) and asthma group (Group A). 95% CI for each group is indicated in brackets. P values are indicated for each metabolite, statistical significances (*) are in bold letters
