Critical appraisal of medical research papers

That is, did the study evaluate all outcomes that both the physician and the patient are likely to view as important? He is a Colorado native who returned to school after stints in several non-healthcare related fields.

If not, why might that be? Were the measurements made under standardized—and thus comparable—conditions in all patients? The methods section can be divided into subsections with their own headings; for example, laboratory techniques can be described separately from statistical methods. From first principles We make critical appraisal easy to understand.

Critical appraisal made easy!

In cohort studies without a comparison group, the treatment effect is frequently estimated by the difference between baseline and follow-up measures of the outcome, though such estimates are vulnerable to bias.

If potential confounders are not mentioned in the publication, the critical reader should wonder whether the results might not be invalidated by this type of error.

The Technology Assessment and Guidelines Unit located in Southern California is available to assist KP physicians in reviewing the evidence for existing and emerging medical technologies.

For the sake of conciseness, detailed description of statistical methods is omitted. Reading the abstract is no substitute for critically reading the whole article, but shows whether the authors have succeeded in summarizing aims, methods, results, and conclusions.

I have attempted to list the questions based on the sections most commonly present in a journal article, starting at the introduction and progressing to the conclusion.

This publication bias leads to systematic distortions in the body of scientific knowledge. A more appropriate comparison would involve other health care interventions aimed at reducing lung cancer mortality, including patient counseling and behavioral or pharmacologic interventions aimed at smoking cessation.

Unfortunately, greater importance is still often attached to significant results, so that they are more likely to be published than nonsignificant findings. In both cases, careful economic evaluation is required to decide whether to modify or retain existing practices.

If these are not obvious, it can be difficult to determine which patients the results apply to, the nature of the change in practice that the article proposes, and whether the intervention produces effects that both physician and patient consider important.

Possible distortion of the study results by missing values should also be discussed. Sadly, not even in science are all terms always used correctly.Moreover, this skill, known as critical appraisal, appears to be lacking amongst consumers of medical research.

Certainly the literature on complemen- tary medicine research - for example, the large number of papers focusing on methodology1 - is devoid of infor- mation on critical appraisal.
