Forward Cox logistic regression analysis of selected variables: multivariate analysis for proportional hazard (dependent variable: residual gradient)
| Variable | β | Wald | df | R | HR (95% CI) | p Value |
|---|---|---|---|---|---|---|
| Model significance: overall score (2 df) = 15.61, −2 LLR = 43.53, p = 0.0004. | ||||||
| β, regression coefficient; df, degrees of freedom; CI, confidence interval; HR, exponential function of β coefficients using natural log 2.74, numerically equivalent to hazard ratio; –2 LLR,–2 log likelihood ratio of the model; Wald, Wald χ2 test. | ||||||
