Colonoscopy Adenoma Detection Trial Data from Japan, 2020-2023

A multicenter randomized controlled trial conducted at six centers in Japan between November 2020 and November 2023. It compares linked color imaging (LCI) and narrow-band imaging (NBI) for detecting adenomas and polyps in the right colon, analyzing data from 1,528 patients. The dataset was published by figshare admin karger under a CC-BY-4.0 license.

Use Cases

• Compare adenoma detection rates (ADR) between linked color imaging and narrow-band imaging based on the trial results.
• Analyze polyp miss rates in the right colon based on the secondary white-light imaging findings.
• Investigate factors influencing lesion miss rates based on variables like bowel preparation quality and endoscopist expertise mentioned in the description.
• Benchmark computer vision models for polyp detection against human performance metrics from this clinical trial.

Strengths

• Data originates from a multicenter randomized controlled trial involving 1,528 patients.
• Results include specific performance metrics such as a 26.7% ADR for LCI and a 31.4% miss rate for adenomas with NBI.
• The study design includes secondary observation with white-light imaging to calculate miss rates.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 200.0 KB, indicating limited scope, likely containing summary results rather than patient-level data.
