Table 1: Patient population demographics

	ESRD all	ESRD+DM	ESRD-DM	TJA all	TJA+DM	TJA-DM
Sample size	82	51	31	39	9	30
Age	65	68	60	68	65	68
Gender (%female)	54	60	45	60	0	70
BMI	29	31	27	32	34	31
HTN	96%	100%	90%	80%	90%	70%
MetS	84%	92%	70%	66%	88%	57%

Most demographics are consistent among the ESRD populations. There is a substantial difference between ESRD+DM and ESRD-DM for MetS, which can be attributed to the fact that insulin resistance is one of the criteria for MetS. Age and BMI are similar in all three TJA populations, while HTN, MetS and gender are different in TJA+DM compared to TJA-DM.
