Early Positive Results in Clinical Trials Exaggerate Long-Term Effects

RedTracker| An international study of nearly 100 clinical trials that were stopped early due to positive treatment results didn’t deliver the expected benefits on a long-term basis.

“On average, treatments with no effect would show a reduction in relative risk of almost 30 percent in stopped early trials. Treatments with a true relative risk reduction of 20 percent would show a reduction of over 40 percent.”

The study’s authors discuss decisions affecting the decisions to stop the trials early from doctors wanting to save lives to the desire of pharma companies to bring new drugs to market ahead of schedule. via Science Daily
