Data Sheet 1_Fecal hemoglobin concentration as a risk stratification tool for advanced col

7,097 residents from the Shanghai colorectal cancer screening program were enrolled, with participants completing both a quantitative fecal immunochemical test (qFIT) and colonoscopy. The study, authored by Xiaocong Zhang and last updated in May 2026, analyzes the association between fecal hemoglobin concentration and the risk of advanced colorectal neoplasm. Logistic regression models were used to calculate odds ratios for risk across different f-Hb concentration thresholds.

Use Cases

• Training risk stratification models based on quantitative fecal hemoglobin (f-Hb) concentration.
• Analyzing the association between f-Hb levels and advanced neoplasm odds ratios derived from logistic regression.
• Conducting subgroup analyses for risk stratification by age and sex categories mentioned in the study.

Strengths

• Study includes 7,097 participants from a community-based screening program.
• Analysis provides specific odds ratios (e.g., 24.21-fold increased risk for f-Hb ≥800 ng/mL) for risk stratification.
• Results are published under a CC-BY-4.0 license, permitting reuse.

Limitations

• The dataset is a 213.9 KB PDF; the underlying tabular data structure and column definitions are not provided.
• Row count for the analytical dataset is unknown, limiting assessment of scale.
• Data reflects a specific screening program in Shanghai, which may limit generalizability.
