According to the same study, the link between blood types and blood clots might come from the fact that people with blood type O have a lower quantity of the von Willebrand factor (VWF), one of the proteins that help the blood clot when needed (for example, to stop bleeding).
The study authors also stated that “because thrombosis is a well-balanced and complex process, which is affected by a plethora of factors, there could be different biological mechanisms (ie, cell functionality, number of cell receptors) involved in the increased risk of thromboembolic events in blood group A and blood B individuals, besides the already established relation with VWF.” This means more research is definitely needed before reaching a final conclusion.
