↵* All identical target lesions chosen by minimum of 2 readers, and target lesions identified by 4, 3, and 2 readers.
↵† If 4 readers selected same target lesion, minimum of 3 readers designated same PSMA-RADS score, and if 3 readers selected same target lesion, minimum of 2 readers designated same PSMA-RADS score.
NA = not applicable.
Data in parentheses are 95% CIs for ICC and percentages for all others.
