They found that nonetheless a broker endpoint trials published in a highest-impact journals frequently demonstrated high efficacy of a tested drug, reduction than one third of them had a clinical outcomes hearing of a drug for a same purpose published. Additionally, when there was a successive clinical outcomes trial, approximately half unsuccessful to countenance a certain impact of a drug on a biomarker. Bikdeli records that while a new commentary usually request to a margin of cardiovascular medicine, doctors and researchers in other fields, such as oncology, reason identical reservations about regulating biomarkers to approve new drugs.
