Intraclass correlation coefficient and the C7 ACC prediction equation from validation data. A Lin's Concordance Correlation Coefficient graphs for GRFVLBW comparison. The solid line represents the 45-degree line of perfect agreement through the origin, while the dotted line is the line of best fit. The spread of data and angle of the line of best fit in the 50–80% HRR (n = 538) illustrate that agreement between ACC predicted is stronger compared to the GRFVLBW.
