Data from each of the diffusion indices were compared by the Randomise 2.1 software [ 22, 23].
To further investigate the external responsiveness changing scores of composite disease activity indices were compared by calculating correlation coefficients.
Differences between the diagnostic performance of the novel index and other non-invasive indices were compared by using ROC curves and the area under the ROC (AUROC) curves.
In addition, the mean changes in VAS that assessed pain and stiffness, as well as Lequesne's functional index were compared by the same test.
A two-year average of SKCS hardness index was compared by significant differences of variance analysis among different genotypes in Chinese landraces and introduced cultivars even though grain texture possessed a high heritability of more than 80% based on previous reports.
The two indexes were compared.
Characteristics of the three patient groups age, weight, height, and body mass index (BMI)—were compared by using the Student's t-test.
DRASTIC and four models derived from it, namely Pesticide DRASTIC, modified DRASTIC, modified Pesticide DRASTIC and Susceptibility Index (SI) were compared by applying them to a weathered rock aquifer in southern India.
Comorbidity categories were defined as normal, moderate, severe, and very severe according to the Charlson comorbidity index, and were compared by means of mortality rate ratios based on Cox regression.
Median values of the indices of differentiation were compared by a Kruskal Wallis nonparametric ANOVA KWW test).
