Intrareader percentage of exact agreement (PEA) expresses the percentage of the patients receiving the same score twice by a single reader, and intrareader percentage of close agreement (PCA) is the percentage of the patients where the 2 readings differ no more than 1.0 in score. Intrareader PEA and PCA are presented as the mean of the 4 readers. Interreader PEA expresses the percentage of the patients receiving the same score by all 4 readers, and the interreader PCA is the percentage of the patients where the difference between the minimum and maximum score is ≤ 1.0. CMC: carpometacarpal; TRM: trapezium; TRD: trapezoid; CAP: capitate; HAM: hamate; SCA: scaphoid; LUN: lunate; TRI: triquetrum; RAD: radius.
