Table 1 Calcium concentration in peritoneal effluent following the long day dwell with and without sodium thiosulfate

	Peritoneal effluent calcium concentration (meq/L)
	Day dwell	CCPD 3 hrs	CCPD 6 hrs	CCPD 9 hrs	Median calcium conc.	Median calcium removal^3
Without sodium thiosulfate^1	–	2.75	2.65	2.45	2.55	0.05
