Comparison of ROC curves between groups providing frozen stool samples (sensitivity analysis restricting group providing frozen samples to participants with documented adherence to requested freezing of stool samples) and fresh stool samples: (A) for detecting CRC, (B) for detecting advanced colorectal neoplasms (CRC or advanced adenomas), and (C) for detecting any colorectal neoplasms. FIT (fresh), FOB Gold using fresh stool samples; FIT (frozen), FOB Gold using frozen stool samples.
