*ICC for numeric parameter; ICC>0.91 showed very good correlation; 0.71<ICC<0.91 showed good correlation; 0.51<ICC<0.71 showed moderate correlation; 0.31<ICC<0.51 showed bad correlation and ICC<0.31 showed very bad correlation.
†κ interpretation: 0.81–1: almost perfect (very good); 0.61–0.80: substantial (good); 0.41–0.60: moderate; 0.21–0.40: fair; 0.00–0.20: slight; <0.00: poor.
