Clinical Epidemiology — Validity, Errors and Biases

Public Health and Epidemiology · Clinical Bases

How it begins

An exhaustive, expert-level treatise on the logical, mathematical, and methodological bases that support epidemiological inference. From the molecular dissection of random and systematic error to the most advanced analytical strategies to neutralize confusion and bias in the era of Big Data and Evidence-Based Medicine.
