SPRINT Study Supplementary Material: Systolic Blood Pressure Burden Analysis

Supplementary material for a post-hoc analysis of the SPRINT clinical trial involving 9,017 high-risk, non-diabetic participants. The research developed and validated a novel systolic blood pressure metric, SBP Burden, for predicting major adverse cardiovascular events over a median follow-up of 3.89 years. The material was authored by figshare admin karger and last updated in April 2026.

Use Cases

• Validate the SBP Burden metric against other SBP indices like Mean SBP, SBP SD, and SBP TTR based on the described methodology.
• Reproduce the statistical analysis for cardiovascular outcome prediction based on the hazard ratios and confidence intervals provided.
• Study the relationship between blood pressure control consistency and major adverse cardiovascular events (MACEs) in a high-risk cohort.
• Assess feature importance and model improvement metrics like Net Reclassification Improvement for novel clinical biomarkers.

Strengths

• Analysis is based on a substantial cohort of 9,017 participants from the SPRINT trial.
• The novel SBP Burden metric is directly compared against five established SBP indices with reported hazard ratios.
• Results include specific performance metrics like a Net Reclassification Improvement of 0.12.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 5.9 MB DOCX, which may require format conversion for computational analysis.
