Mortality and health-related quality of life in prevalent dialysis patients: Comparison between 12-items and 36-items short-form health survey

Table 4 Unadjusted and multi-adjusted hazard ratios (HRs) for mortality were assessed for patients on dialysis (n = 252) grouped by continuous physical and mental component scores (PCS-36, MCS-36, PCS-12, and MCS-12), based on the SF-36 and SF-12

	Unadjusted HR (95% CI)	p-value	Adjusted HR (95% CI)	p-value
PCS-36 (per one increment unit)	0.963 (0.943, 0.984)	0.001	0.977 (0.953, 1.002)	0.077
PCS-12 (per one increment unit)	0.954 (0.931, 0.977)	<0.001	0.968 (0.942, 0.995)	0.022
MCS-36 (per one increment unit)	0.989 (0.970, 1.008)	0.248	0.995 (0.976, 1.015)	0.649
MCS-12 (per one increment unit)	0.981 (0.961, 1.001)	0.057	0.989 (0.968, 1.011)	0.339

The PCS-36 and PCS-12 were adjusted for age, gender, Charlsons comorbidity index without age, log transformed dialysis vintage, and albumin. The MCS-36 and MCS-12 are adjusted for age, gender, Charlsons comorbidity index without age, log transformed dialysis vintage, and hemoglobin.
