Table 5.

Cox proportional hazards model for survival in patients treated by dialysis. Increasing age, the presence of diabetes and the presence of high comorbidity are significant predictors of mortality in this group of patients. Numbers in square brackets indicate the number of patients in each category

Chi square = 131 (P < 0.001)	P-value	Hazard ratio	95% CI for HR
Chi square = 131 (P < 0.001)	P-value	Hazard ratio	Lower	Upper
Gender (female [293] compared with male [551)	0.752	0.965	0.771	1.207
Ethnicity (non-white [132] compared with white [712])	0.261	1.201	0.873	1.651
Diabetes (diabetic [291] compared with non-diabetic [553])	0.000	1.604	1.293	1.990
Comorbidity (high [196] vs low [648])	<0.001	2.214	1.732	2.830
eGFR at stage 5 (mL/min/1.73 m²)	0.258	0.959	0.891	1.031
Age at stage 5 (years)	<0.001	1.033	1.024	1.043
