Complete thrombus resolution, freedom from recurrent VTE, and freedom from VTE-related death.
Defined as any symptomatic or asymptomatic contiguous progression of the index thrombus.
PTS (newly identified or worsening from baseline) was not specified as an outcome in the acute treatment study but was reported as an AE within the treated set.
