Study design in medical research: part 2 of a series on the evaluation of scientific publications.
Background: The scientific value and informativeness of a medical study are determined to a major extent by the study design. Errors in study design cannot be corrected afterwards. Various aspects of study design are discussed in this article. Methods: Six essential considerations in the planning an...

Errors in study design cannot be corrected afterwards. Various aspects of study design are discussed in this article. Methods: Six essential considerations in the planning and evaluation of medical research studies are presented and discussed in the light of selected scientific articles from the international literature as well as the authors' own scientific expertise with regard to study design. Results: The six main considerations for study design are the question to be answered, the study population, the unit of observation, the type of study, the measuring technique, and the calculation of sample size. Conclusions: This article is intended to give the reader guidance in evaluating the design of studies in medical research. This should enable the reader to categorize medical studies better and to assess their scientific quality more accurately. pubtype: Academic Journal doctype: review tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
