Fig. 2From: The differential effect of modern intravenous iron on fibroblast growth factor 23 and phosphate in non-dialysis dependent CKD – the exploratory randomized controlled double-blind ExplorIRON-CKD studyBox plots representation of %change in iFGF23 following intervention with FDI or FCM. Legend: %change iFGF23 following infusion with FDI or FCM. Statistically significant larger %change (increase) where FCM was infused, between baseline and 1–2 days following 1st infusion and baseline and 2nd infusion. This was reflected in the significantly higher iFGF23 concentration 1–2 days following 2nd infusion in those administered FCM when compared to those receiving FDI.
