Table 2 Inter-session variability of the selected parameters. t1, ...., t4 represent four consecutive EBC collections from 10 healthy subjects. No significant differences were found using repeated measures ANOVA followed by Tuckey's post-hoc test. MDA was excluded from the analysis because its reliability has been previously measured [15,16]. Mean ± SD or geometric mean [geometric SD] are also reported.
