Glycated Hemoglobin and In-Stent Restenosis Risk in 6,297 CAD Patients

A retrospective study of 6,297 coronary artery disease patients following percutaneous coronary intervention, examining the association between glycated hemoglobin (HbA1c) levels and the risk of in-stent restenosis. The dataset likely contains patient-level clinical variables and outcomes, with 1,305 individuals (20.72%) diagnosed with ISR. It was authored by Yuyang Lei and last updated on figshare in April 2026.

Use Cases

• Modeling the non-linear relationship between HbA1c levels and ISR risk based on the threshold effect analysis described.
• Training risk prediction models for post-PCI complications using the described cohort of 6,297 patients.
• Conducting stratified analyses to test for effect modification by additional clinical variables as mentioned in the methods.
• Replicating the adjusted logistic regression models assessing the association between HbA1c levels and ISR.

Strengths

• Includes data from a substantial cohort of 6,297 patients.
• Provides specific outcome proportions, including 1,305 ISR cases (20.72%).
• Results include detailed statistical measures such as odds ratios (e.g., OR:1.70) and confidence intervals.

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 (18.4 KB), suggesting limited scope, possibly containing only summary results rather than raw patient data.
