FOBT was performed using an OC-sensor kit (EIKEN Chemical Co. Ltd., Tokyo, Japan), according to the manufacturer’s instructions, by researchers blinded to the source of each sample. The FOBT used in this study did not require dietary restrictions. The analytical cut-off for FOBT positivity was 100 ng Hb/ml.

The specimen for FIT (OC-Sensor kit; Eiken Chemical, Tokyo, Japan) was obtained and sent to the hospital within 1 week before the examination. The results are expressed in nanograms of hemoglobin per milliliter buffer (ng Hb/mL), and the cutoff value of positivity was set at 100 ng Hb/mL.
All colonoscopies were performed by well-experienced endoscopists who had performed >1,000 colonoscopy examinations, with ≥300 procedures conducted annually, using the EvisLucera CV-260 colonoscope (Olympus Medical Systems, Tokyo, Japan). Bowel preparation regimens were split-dose sodium phosphate or 2 L of polyethylene glycol solution. During the examination, the decision of biopsy, snare polypectomy, or endoscopic mucosal resection for the colorectal neoplasm was at the discretion of the endoscopist. However, the presence of adenoma, advanced adenoma, or CRC was diagnosed through histologic evaluation. In the case of difficult-to-treat polyps, subsequent endoscopic or surgical resection was performed within 6 months after index colonoscopy. Accordingly, polyps and lesions that were not removed at our institute within 6 months of index colonoscopy were not included in the analysis, regardless of endoscopic diagnosis.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
