Table 7.

Comparative study of AccID for our best ID model (validation results) and the results reported by other authors over databases with different number of subjects (the databases’ abbreviations are cited according to their reference in the source publication). The information about single or multiple recordings per patient (srpp or mrpp) and the interval between T1 and T2 (in case of mrpp) is provided.
