Statistics
Descriptive statistics analysis was done. The IBM SPSS Version 23.0 was used for all statistical analyses. Descriptive analysis values were of median and interquartile range of each CPG, as well as the mean in percentage (%) across domains. In order to measure agreement among reviewers, intra-class correlation coefficients (ICC) were calculated, with the following values:
Model: Two-way random, Type: Absolute agreement, Confidence interval: 95%.
ICC values above 0.75 were considered to represent good reliability and agreement among reviewers14-15.
