Stepwise multiple logistic regression analysis of factors independently associated with a background history of heart failure
| Factors | Odds Ratio (95% CI) | P |
|---|---|---|
| Diabetes | 3.14 (1.47 to 6.69) | 0.003 |
| Background AVD | 3.88 (1.73 to 8.71) | 0.001 |
| LV mass index (g/m2) | 1.006 (1.001 to 1.010) | 0.01 |
| Age (years) | 0.96 (0.93 to 0.99) | 0.02 |
| Serum albumin (g/L) | 0.92 (0.86 to 0.99) | 0.02 |
| E/Em ratio | 1.05 (1.01 to 1.09) | 0.02 |
| Male gender | 1.96 (0.96 to 4.01) | 0.07 |
| Hemoglobin (g/dl) | 0.83 (0.67 to 1.03) | 0.09 |
Out of the model with dialysis vintage, daily urine volume, body mass index, residual GFR, and LV EF. Age, gender, and dialysis vintage were regarded as important confounding covariates and were considered in the multiple regression analysis irrespective of their P values in univariate analysis.
