Selected laboratory values prior to INHD conversion and 6 and 12 months following INHD conversion

	Pre-conversion (n = 37)	Six months following INHD conversion (n = 37)	Twelve months following INHD conversion (n = 31)
Reduction in urea, %	71.7 ± 6.7	84.9 ± 6.3*	86.7 ± 6.4*
Hemoglobin, in g/L	114.5 ± 17.3	119.1 ± 14.8	117.1 ± 13.5
Serum albumin, in g/L	33.7 ± 3.5	33.3 ± 3.0	32.8 ± 4.4
Calcium, in mmol/L	2.12 ± 0.23	2.20 ± 0.12*	2.18 ± 0.17
Phosphate, in mmol/L	2.10 ± 0.59	1.57 ± 0.49*	1.46 ± 0.47*
PTH, in pmol/L	26 (20-41)	28 (15-74)	36 (17-61)
ALP, in Units/L	95 (63-138)	124 (105-167)*	144 (92-212)*

Data are presented as means ± standard deviation or medians (interquartile range), as appropriate. The paired t-test was used to compare pre- and post-conversion differences for normally-distributed variables and the signed rank test was used for non-normally distributed variables.

* denotes p-value of < 0.05 for change in the laboratory value as compared to pre-conversion to INHD
