Table 2 Parameter estimates in the final models and risk score

From: A new risk scoring system for prediction of long-term mortality in patients on maintenance hemodialysis

Variables Parameter estimate in the final model Ratio Score
Older 0.96 2.97 3
DM 0.85 2.63 3
Hypotension 0.41 1.25 1
High CTR 0.38 1.16 1
High BNP level 0.32 1 1
ECG score = 1 0.46 1.43 1
ECG score = 2 1.52 4.69 5
  1. Each parameter estimate in the final models was compared with the smallest parameter estimate (High BNP level). Then, the risk scores were determined.
  2. Older 65 ≤ age, DM diabetes mellitus as a cause of end-stage renal disease, Hypotension hypotension during hemodialysis, High CTR 50 % ≤ cardiothoracic ratio, High BNP level 250 pg/mL ≤ plasma brain natriuretic peptide level, ECG score the number of abnormal findings in electrocardiogram
