To the Editor: Dr Guyatt and colleagues1 suggest a hierarchy of study design to evaluate the strength of evidence for making treatment decisions. In promoting the superiority of single randomized trials over systematic reviews of observational studies, the authors risk making the same mistake that evidence-based medicine professes to avoid—relying on personal experience and disregarding the best available evidence.
