Study flow chart. Among the 4,245 evaluable participants, 186 participants were diagnosed with CRC (4.4% prevalence), and 375 participants were found to have advanced precancerous neoplasia (8.8% prevalence). Despite the fact that 55.7% of the overall participants were females, 104 (55.9%) participants who had CRC and 241 (64.3%) participants who had advanced precancerous neoplasia were males (Table 1). Among the participants with confirmed CRC, 85 participants had early‐stage CRC (Stages I to II), and 140 participants had CRC Stage I to III. CRC was found more frequently in the distal section of the colon than the proximal section (154 vs. 32). Details of the clinical findings are shown in Table S1 (in the Appendix, Supporting information). CRC, colorectal cancer.
