Randomized, Double-Blind, Controlled, Multicenter, Large-Sample Studies, December 27, 2004

Randomized, double-blind, controlled, multicenter, large-sample studies are modern evidence-based medicine methodologies. Before applying these methods, collecting “evidence” is of paramount importance; evidence is the core of evidence-based medicine, and its accuracy determines the success of evidence-based practices. Evidence is categorized into five levels based on its degree of certainty, each with different origins, varying degrees of precision, and distinct analytical methods. In short, evidence-based medicine can only be conducted in the modern era with computer networking.
