Table 2 Changes of serum potassium(mmol/L) before and after treatment

	IG group	SPS group	SZC group	IG + SZC group	P
Serum potassium before treatment, M (Q1, Q3)	5.85 (5.64,6.09)	5.96 (5.70,6.24)	6.01 (5.74,6.27)	6.56 (6.37,7.08)	< 0.001^a
Serum potassium after treatment M (Q1, Q3)	5.20^c (4.90,5.49)	5.38^c (5.27,6.07)	5.32^c (5.00,5.74)	5.30^c (4.65,5.53)	0.016^b
Decrease of serum potassium	0.71 ± 0.32	0.43 ± 0.38	0.64 ± 0.36	1.43 ± 0.38	< 0.001^a
Dispersion coefficient (CV) of serum potassium decline	45%	89.3%	56.8%	26.9%
The rate of serum potassium decline (%)	11.89 ± 5.19	7.12 ± 6.32	10.58 ± 6.07	21.51 ± 5.74^a	< 0.001
The standard-reaching rate of serum potassium (cases/%)	35 (76.1%)	19 (57.6%)	21 (55.3%)	15 (68.2%)	0.176
Control rate of severe hyperkalemia (cases/%)	7 (100%)	6 (60%)	11 (91.7%)	18 (100%)	0.135^d

^aThere was no significant difference between IG and SZC groups in pairwise comparison, and the rest were statistically significant (P < 0.05)
^bIn pairwise comparison, there was no significant difference except IG group and SPS group (P < 0.05)
^cStatistically significant difference compared with pretreatment (P < 0.05)
^dP value of SPS group compared with SZC group
