Epidemiology — Introduction and Fundamentals
Public Health and Epidemiology · Clinical Bases
How it begins
Un compendio exhaustivo y riguroso de la ciencia de la salud de las poblaciones. Desde el análisis formal de los modelos de causalidad de Hill, Rothman y los modelos contrafácticos, hasta la deducción matemática de los parámetros bioestadísticos, el control de la confusión, sesgos sistemáticos, la teoría de cribado diagnóstico y las metodologías contemporáneas de síntesis de evidencia científica.
