Dataset for "Three-year risk of colorectal cancer by faecal haemoglobin concentration in subjects with a negative fit: is one test enough?"

This repository contains two Stata (.dta) files used for the analyses presented in the manuscript "Three-year risk of colorectal cancer by faecal haemoglobin concentration in subjects with a negative fit: is one test enough?". The datasets include all variables analyses. These data were created during the stusy and are provited for transparency and reproducibility.本仓库收录两份Stata格式（.dta）数据文件，用于支撑研究论文《粪便血红蛋白浓度与粪便免疫化学检测（Fecal Immunochemical Test, FIT）阴性受试者的结直肠癌三年发病风险：单次检测足够吗？》中的分析工作。数据集涵盖本次分析所需的全部变量，本批数据由本研究过程中生成，旨在通过公开共享以提升研究透明度与结果可复现性。
