| Model 1* | Model 2** | ||||
|---|---|---|---|---|---|
| Clinical predictor of AD | Odds ratio (OR) | 95% CI range | Clinical predictor of AD | Odds ratio (OR) | 95% CI range |
| BMI Z-score | 0.52 | 0.35 – 0.78 | BMI Z-score | 0.47 | 0.26 – 0.84 |
| Presence of glomerular disease | 4.58 | 1.45 – 14.46 | Presence of glomerular disease | 12.34 | 1.9 – 79 |

BMI = body mass index; BP = blood pressure; Ca × P = calcium × phosphorus product; DBP = diastolic blood pressure; Hgb = hemoglobin; iPTH = parathyroid hormone; SBP = systolic blood pressure. *Model 1 includes the covariates of p-vales ≤ 0.15 in univariate analysis (Table 1). The hemodialysis parameters of normalized interdialytic weigh gain and normalized ultrafiltration were not included in the model because these values are available for less than 50% of the cohort (37/97 patients). **Model 2 includes the variables in model 1 in addition to other clinical variables that are known to be associated with cardiovascular and morbidity risk in ESRD population.
