Calculation of the DCS by Assigning Different Weighting Factors to the Confidence Levels

	DCS = N_dnl − 0.25 × N_lnl − 0.5 × N_pnl − 0.75 × N_possnl − N_sc1l − 0.75 × N_poss1l − 0.5 × N_p1l − 0.375 × N_ql1l − 0.25 × N_hl1l + N_d1l
N_dnl	No. subjects with “definitely no lesions” of this criterion
N_lnl	No. subjects with “likely no lesions” of this criterion
N_pnl	No. subjects with “probably no lesions” of this criterion
N_possnl	No. subjects with “possibly no lesions” of this criterion
N_sc1l	No. subjects with “small chance of 1 or more lesions” of this criterion
N_poss1l	No. subjects with “possibly 1 or more lesions” of this criterion
N_p1l	No. subjects with “probably 1 or more lesions” of this criterion
N_ql1l	No. subjects with “quite likely 1 or more lesions” of this criterion
N_hl1l	No. subjects with “highly likely 1 or more lesions” of this criterion
N_d1l	No. subjects with “definitely 1 or more lesions” of this criterion

DCS indicates diagnostic confidence score.
