Regarding Registration of Clinical Trials

Arch Ophthalmol. 2007;125(6):853. doi:10.1001/archopht.125.6.853-a

It is with great interest that I read the editorial by Levin et al1 on the registration of clinical trials in the September 2005 issue of the Archives.

It is not quite clear to me how registering studies will improve ethics—unless there is a controlling agency that makes sure the results of each study will be submitted and then also accepted for publication (so far, negative results are much less likely to be accepted for publication by reviewers).
