Reply: Request for clarification on symptom assessment methodology in high‐risk population colonoscopy study.

We would like to express our gratitude to Safari, Farzad, and Noursina, Ali, for their insightful comments about our article regarding the questionnaire procedure and the assessment of symptoms, including a history of chronic constipation, chronic diarrhea, and mucous blood stools. This questionnaire has been included in national screening programs since 2007 and has been used in many cities in China.[[1], [3]] Since 2012, CRC screening in community allied third-grade class-A hospitals has been initiated in Tianjin City, China. As stated in the manuscript, only 39.41% of the screening population completed a colonoscopy within 1 month, so those with symptoms at the time of initial screening were advised to seek a definitive diagnosis promptly and were excluded from screening.
