This type of study includes a small number of participants so it is not expected to prove how safe the treatment is or how well the treatment works.\n\nThe main question it hopes to answer is:\n\n1.What is the average number of patients that are recruited per month during the 12 month study period?\n\nTo test the study plan, adults being treated for a superficial vein thrombosis (SVT), which is a blood clot in the superficial veins of the leg, will be given a type of blood thinner called rivaroxaban. Half of the participants in this study will be given the standard (low-dose) rivaroxaban for 45 days, then 45 days of placebo (a substance that looks like the study medication but does not have any active or medicinal ingredients). The other half of participants will be given full-dose rivaroxaban for a total of 90 days. The placebo in this study is not intended to have any effect on the participants blood clot.
