Fig. 3From: The oxygen reactivity index indicates disturbed local perfusion regulation after aneurysmal subarachnoid hemorrhage: an observational cohort studyScatterplot of Pressure Reactivity Index (PRx) versus Oxygen Reactivity Index (ORx). Light gray dots represent hourly data pairs from all patients, and dark gray dots represent one averaged data pair per patient for the entire analyzed period. Spearman’s rank correlation depicts the lack of correlation between PRx and ORxBack to article page
