Ex Input:
Question: Does polymorphism of the glycoprotein Ia and IIIa in the group of women in childbirth correlate with an increased risk of developing thrombosis?
Answer: Our results did not show the causative relationship between the existence of platelets GP IIIa/GP Ia mutations and venous system thrombosis in the women in labor. Probably presence of pro-thrombotic mutations of platelets glycoprotein in this group of patients does not represent the increased risk of thrombosis.

Ex Output:
no


Ex Input:
Question: Does changing Default Fluoroscopy Equipment Settings decrease Entrance Skin Dose in Patients?
Answer: Radiation safety training protocols improved clinical knowledge but did not significantly alter fluoroscopy time. Changing equipment default settings to intermittent pulse rate (12 frames per second) and half-dose lowered the entrance skin dose by 30% across all endourology patients but most significantly during percutaneous nephrolithotomy. To limit patient radiation exposure fluoroscopy default settings should be decreased before all endourology procedures and image equipment manufacturers should consider lowering standard default renal settings.

Ex Output:

yes
