The company reported only the top-line figure in a press release Tuesday, and did not break out the reductions it said were seen in heart attacks, strokes, and cardiovascular deaths — the combined components of the study’s primary outcome. It said all three contributed to the decrease in cardiovascular events in the group that received Wegovy compared with participants given a placebo.
