Clinical tests and measurements

Abstract

Statistical analysis and comparison results between current 2D assessment method and the proposed 3D method are conducted. In this section, we will analyze the degree of association, limits of agreement and repeatability of measurements for both 2D and 3D methods comparison. Intra-observer variability is tested to answer the repeatability skills between operators’ measurements. Pearson’s correlation value can be computed to evaluate the relationship between existing method and proposed new method. Levels of agreement between methods are analyzed using Bland–Altman’s test on three varied grouping observations. Repeatability coefficient is calculated to evaluate the measurements repeatability between the methods. This chapter looks into the test for the measurement results of proposed method. The findings are evaluated with the existing 2D measurement method. It includes the descriptive analyses, degree of association, limits of agreements, Paired sample t-test and repeatability between the methods.
