PET/CT interobserver agreement in DLBCL
Percentage exact agreement = ((88 + 43 + 21 + 38 + 24)/465)*100% = (214/465)*100% = 46.0%. Percentage agreement (+1, -1) = ((88 + 43 + 21 + 38 + 24 + 46 + 40 + 20 + 26 + 8 + 10)/465)*100% = (364/465)*100% = 78.3%.
Percentage exact agreement = ((128 + 37 + 16 + 16 + 23)/457)*100% = (220/457)*100% = 48.1%. Percentage agreement (+1, -1) = ((128 + 37 + 16 + 16 + 23 + 57 + 49 + 17 + 16 + 14 + 8)/457)*100% = (381/457)*100% = 83.4% .
