In plain words

What the trial is, and whether it could suit you

This four-group prospective study will enroll travelers who have independently booked economy or premium business/first-class flights to Bogota. Within each cabin stratum, participants will be randomized to moderate graduated compression stockings or no stockings. Bilateral popliteal vein ultrasound will be performed before flight, within 2 hours after arrival, and at 24 and 48 hours. The primary outcome is the interaction between cabin class and compression assignment for change in mean bilateral popliteal vein diameter.
