Fig. 4From: HS-GC–MS analysis of volatile organic compounds after hyperoxia-induced oxidative stress: a validation studyUntargeted analysis of volatile organic compounds (VOCs). Volcano plot (A) with the relative change of the median intensity of VOCs from the headspace of hyperoxia-exposed cells compared to controls is shown on the x-axis and the false discovery rate-adjusted P value on the y-axis. VOCs with at least a twofold increase of the median and an adjusted P value < 0.05 are labelled and their change per group is shown (B–F)Back to article page
