Szklo & Nieto's Epidemiology: Beyond the Basics offers a deeper exploration of epidemiologic principles for readers who already grasp the fundamentals of analytic methods. Moving beyond introductory concepts, the book provides a rigorous yet accessible discussion of study design, measures of association, research evaluation, and other essential components of epidemiologic investigation. Through real-world examples and an emphasis on practical interpretation rather than complex statistical formulas, it serves as an invaluable resource for intermediate students and practicing epidemiologists seeking to broaden their expertise and strengthen their understanding of epidemiology’s critical role in medical and public health research. Incorporating the latest research and methodologies, the Fifth Edition reflects the current state of epidemiology. Additionally, this comprehensive text provides 3 new chapters:- Chapter 1: “Selected Underlying Concepts in Analytic Epidemiology”- Chapter 9: “Tools for Addressing Selection Bias”- Chapter 11: “Efficient Study Designs”
