^aP value is the P value of the comparison results of the diagnostic performance between simplified liver imaging reporting and data system (sLI-RADS) A and liver imaging reporting and data system (LI-RADS) v2018, respectively.

^bP value is the P value of the comparison results of the diagnostic performance between sLI-RADS B and LI-RADS v2018, respectively.

^cP value is the P value of the comparison results of the diagnostic performance between sLI-RADS C and LI-RADS v2018, respectively.

^dP value is the P value of the comparison results of the diagnostic performance between sLI-RADS D and LI-RADS v2018, respectively.

^eP value is the P value of the comparison results of the diagnostic performance between sLI-RADS E and LI-RADS v2018, respectively.

^fP value is the P value of the comparison results of the diagnostic performance between F-sLI-RADS and sLI-RADS D.

“—”: Indicates no data. PPV: Positive predictive value; NPV: Negative predictive value; LI-RADS: Liver imaging reporting and data system; sLI-RADS: Simplified liver imaging reporting and data system; F-sLI-RADS: Final simplified liver imaging reporting and data system.
