Analyses and Concerns in Precision Medicine: A Statistical Perspective

TL;DR

This paper surveys the role of statistical analysis in precision medicine, detailing how core methodologies—ranging from traditional hypothesis testing to high-dimensional modeling and Bayesian inference—are applied to integrate genomics, EHRs, and other data. It discusses data integration challenges, ethical and privacy considerations, and the evolving regulatory landscape, while highlighting AI-driven directions and interpretability concerns. The historical perspective traces the field from early statistical foundations through the Human Genome Project to modern, data-intensive approaches. Case studies in oncology, cardiovascular, and neurological diseases illustrate how data fusion and rigorous statistics enable biomarker discovery and personalized therapies with significant clinical impact.

Abstract

This article explores the critical role of statistical analysis in precision medicine. It discusses how personalized healthcare is enhanced by statistical methods that interpret complex, multidimensional datasets, focusing on predictive modeling, machine learning algorithms, and data visualization techniques. The paper addresses challenges in data integration and interpretation, particularly with diverse data sources like electronic health records (EHRs) and genomic data. It also delves into ethical considerations such as patient privacy and data security. In addition, the paper highlights the evolution of statistical analysis in medicine, core statistical methodologies in precision medicine, and future directions in the field, emphasizing the integration of artificial intelligence (AI) and machine learning (ML).
