Analysis Finds Clinical Trials Often Small, of Poor Quality – MedicineNet

Worrisome.

Studies of cancer treatments, in particular, often fail to follow the highest standards of medical research, the analysis found. Meanwhile, a full 7 percent of the studies didn’t bother to mention their purpose, while others failed to provide other important details.

…. the analysis found that most clinical research in the (Clinicaltrials.gov) database isn’t very extensive, raising questions about reliability.

The new report says 62 percent of the trials from 2007-2010 were small, with 100 or fewer participants. Only 4 percent had more than 1,000 participants…..

Ideally, medical studies compare randomly chosen groups of people to each other, with one group getting a treatment and the other getting another treatment or an inactive placebo. However, 65 percent of cancer studies didn’t randomize their participants, compared to 26 percent of cardiovascular studies.
