Fig. 2.

Clinical parameters affecting HNA% determined by multivariate analysis. Left panel indicates the least-square regression line between the predicted values and the actual measurements of HNA%. Area shaded in red represents the 95% CI confidence interval. The average of the HNA% measurements is displayed as a blue line. The root mean squared error (RMSE) is 3.7446, and the correlation coefficient (R) is 0.663. Right panel shows coefficients and standard errors (SE) of statistically significant parameters.
