Fig 2. Day 1 plasma FGF23 concentrations stratified by the presence or absence of Day 3 AKI.

Fig 2

Day 1 plasma total fibroblast growth factor 23 (cFGF23) concentrations were significantly higher in subjects who had acute kidney injury (AKI) on Day 3 than in those that did not (Fig 2A). Day 1 plasma intact FGF23 concentrations were not significantly different between the two groups (Fig 2B). Data are presented as medians and interquartile ranges, and the Wilcoxon rank-sum test was used to compare groups.
