Gold standard | Acceptable | Inappropriate |
---|---|---|
• Bland-Altman plot/limits of agreement (LOA) analysis • Intraclass correlation coefficient • Lin’s concordance correlation coefficient • British standards reproducibility/repeatability coefficient For all methods in this category, if repeat measurements per patient have not obviously been accounted for, then classify as acceptable. |
• Mean square error/deviation • Root mean square error/deviation • Mean absolute error/deviation • Accuracy • Categorisation (e.g. proportion of time/measurements test within a threshold of gold standard) • Descriptive only—plot of test against gold standard, or test and gold standard signals overlaid |
• (Pearson’s) correlation coefficient • T test |
