Fig. 2From: HS-GC–MS analysis of volatile organic compounds after hyperoxia-induced oxidative stress: a validation studyTargeted analysis of volatile organic compounds (VOCs) associated with oxidative stress. Volcano plot 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 previously associated with oxidative stress that could be identified by gas standard are labelledBack to article page
