Multivariable logistic regression analysis of factors associated with frailty.
| Variables | OR | 95% CI | P |
|---|---|---|---|
| Age (years) | 2.921 | 1.553-2.384 | <0.001* |
| DM | 1.008 | 0.997-1.006 | 0.382 |
| CVD | 0.855 | 0.312-2.320 | 0.753 |
| CAD | 0.911 | 0.520-1.583 | 0.737 |
| Hb (g/l) | 2.514 | 1.132-4.297 | 0.026* |
| Albumin (g/l) | 2.863 | 1.695-5.102 | 0.015* |
| P (mmol/l) | 0.965 | 0.659-1.582 | 0.401 |
| Uric acid (umol/l) | 0.872 | 0.772-0.995 | 0.032* |
| DBP after HD (mmHg) | 1.334 | 1.073-1.688 | 0.011* |
| ultrafiltration volume/dry weight (no groups) | 1.289 | 1.087-1.531 | 0.035* |
| ultrafiltration volume/dry weight (3 groups) | 1.725 | 1.101-1.425 | 0.019* |
Abbreviations: BMI, body mass index; DM, diabetes mellitus; CVD, cerebral vascular disease; CAD, coronary artery disease; Hb, hemoglobin; DBP, diastolic blood pressure; HD, hemodialysis; OR, odds ratio; 95%CI, 95% confidential interval.
* P< 0.05
Note: grouping of ultrafiltration volume /dry weight: ≤ 0.039, 0.039-0.050, ≥0.050. 0.039 is the average ratio of ultrafiltration volume to dry weight in non-frail group and 0.05 is a well-known clinical safety standard.
