Clinical Correlation Analysis and Statistical Modeling

This contract involves the quantitative analysis of skin photoplethysmography (SPG) features and their statistical correlation with key clinical markers including arterial compliance, vascular age, and heart rate variability. The work requires advanced statistical modeling techniques to identify and validate relationships between non-invasive SPG-derived signals and established indicators of cardiovascular health, with the goal of enhancing predictive capabilities and clinical applicability. The analysis must be rigorous, reproducible, and aligned with current biomedical research standards to support potential diagnostic or monitoring applications. The contract is structured as a small business set-aside under the SBA program, classified under NAICS code 541990 for other scientific and technical consulting services. It is issued by the National Institutes of Health under the Department of Health and Human Services with a performance location in Bethesda, Maryland. The solicitation was posted on July 8, 2026, and responses are due by July 18, 2026, with the expectation that only eligible small businesses will submit proposals. The work scope emphasizes methodological precision, data integrity, and the translation of statistical outputs into clinically relevant insights without direct patient interaction or device development.
