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.
