* as reported in http://clinicaltrial.gov/ website, the absence of posted results could be due to the facts that: the study may not be subject to U.S. Federal requirements to submit results, or the study has been completed, but the deadline for results submission has not passed, or the results have been submitted but have not yet been posted (for example, pending review by ClinicalTrials.gov) [44].
