Clinical trials are experimental in their design and conducted under standardized terms, that is, rigorous inclusion and exclusion criteria as well as an artificial trial environment may hamper the transferability of results. Studies designed for approval of new medicines usually exclude elderly patients, multi-morbid patients, pregnant women and children. For example, the median age at diagnosis of colorectal cancer in Germany is 69 (men) and 75 (women) years, respectively. In clinical trials investigating chemotherapy, however, patients above the age of 70 years represent only 18% of the trial population. In cardiovascular trials, especially on acute coronary syndromes, women are usually under-represented. Guidelines derived from clinical trials should therefore explicitly mention a study's limitations. It should be communicated clearly for which patients and under which conditions the guideline is applicable. | | Language | ger | | Pub Type(s) | English Abstract
