(CNN) Blood thinners appear to reduce the risk of death by up to 50% among seriously ill, hospitalized coronavirus patients, researchers reported Wednesday. Their study of more than 4,300 patients also those who died often had evidence of blood clots throughout their bodies, even though many of them had no symptoms of the problem. It's more evidence of the serious, systemwide blood clotting that coronavirus infections can cause, but the findings offer hope of countering the effect. It was not a randomized controlled study, the gold standard for medical research. "An international randomized trial just started with 15 institutions," Fuster told CNN.
