Percent changes in mineral metabolic parameters over the course of the study

Metabolic Parameter	Cinacalcet-D (% Change)	Flex-D (% Change)	P Value of Change Between Groups
Log FGF23	−9.7 ± 18.2	4.1 ± 16.5	0.002
PTH	−29.4 ± 72.9	−10.8 ± 47.2	0.20
Ca	−6.8 ± 9.0	2.0 ± 6.1	<0.0001
P	4.4 ± 32.9	4.0 ± 31.8	0.96

Values shown as mean ± SD.

Within the Cinacalcet-D subjects, percent decreases in log FGF23 and Ca were significant (P = 0.021 and 0.008, respectively); there were no significant within-group changes in the Flex-D subjects.
