Logistical regression for the outcome nonstandard dialysis start

	Odds ratio	95% CI			P value
		Lower	Higher
CCI (≥8)	0.863	0.344	2.150		0.752
BMI (≥30 kg/m2)	0.662	0.254	1.689		0.389
Gender (male)	0.788	0.318	1.888		0.597
Diabetes, NAS vs. others	1.129	0.442	2.895		0.799
eGFR (<7 ml/min per 1.72 m2)	0.279	0.115	0.646		0.004
Urgent vs. planned start	0.254	0.106	0.581		0.002
Intensive predialysis vs. conventional care	10.826	3.452	48.220		<0.001

BMI, body mass index; CCI, Charlson comorbidity index; eGFR, estimated glomerular filtration rate according to the CKD-Epidemiology Collaboration formula; NAS, nephroangiosclerosis.

The Pearson phi coefficient⁶⁴ was equal to 0.271 between urgent start and intensive predialysis care origin (both were kept in the model) and 0.57 between age and CCI, thus only the Charlson score was used.

Bold value indicates significant differences.
