this is from a recent article Poor-Quality Medical Research What Can Journals Do? Douglas G. Altman, DSc The aim of medical research is to advance scientific knowledge and hencedirectly or indirectlylead to improvements in the treatment and prevention of disease. Each research project should continue systematically from previous research and feed into future research. Each project should contribute beneficially to a slowly evolving body of research. A study should not mislead; otherwise it could adversely affect clinical practice and future research. In 1994 I observed that research papers commonly contain methodological errors, report results selectively, and draw unjustified conclusions. Here I revisit the topic and suggest how journal editors can help.JAMA. 2002;287:2765-2767you have to pay for the whole thing but if even JAMA has concerns about researchit's hard to trust what you read on the web from one or two articles.tom
