Eksperimentel: Economy Cabin Plus Compression
Participants with a prebooked economy itinerary randomized to knee-high moderate graduated compression stockings.
|
PROPOSED pressure class: 20-30 mmHg at the ankle, properly fitted and worn from approximately 1 hour before boarding through the arrival ultrasound.
Product and pressure class require confirmation.
Linked arm/group(s): Economy Cabin Plus Compression, Premium Cabin Plus Compression.
Prebooked and completed economy-cabin travel; seat characteristics and behavior are measured but not assigned.
Linked arm/group(s): Economy Cabin Plus Compression, Economy Cabin Without Compression.
Triplicate bilateral diameter and cross-sectional-area measurements before flight and at arrival, 24 hours, and 48 hours by an assessor masked to stocking allocation.
Linked arm/group(s): Economy Cabin Plus Compression, Economy Cabin Without Compression, Premium Cabin Plus Compression, Premium Cabin Without Compression.

|---|---|---|
|
Randomized Compression Stocking Effect on Arrival-Related Diameter Change
Tidsramme: Within 24 hours before departure and within 2 hours after arrival. 3 days
|
Adjusted mean difference between stocking and no-stocking assignments overall and separately within each cabin stratum.
|
Within 24 hours before departure and within 2 hours after arrival. 3 days
|
|
Adjusted Cabin-Class Association With Arrival-Related Diameter Change
Tidsramme: Within 24 hours before departure and within 2 hours after arrival. 3 days
|
Adjusted mean difference between premium and economy cabin groups overall and separately by stocking assignment.
This contrast is observational because cabin class is not randomized.
|
Within 24 hours before departure and within 2 hours after arrival. 3 days

Four-Group Popliteal Vein Diameter Trajectory
Tidsramme: Within 24 hours before departure; within 2 hours after arrival; 24 +/- 2 hours; and 48 +/- 2 hours after arrival. 3 days
|
Estimated mean bilateral diameter and change from baseline in each of the four groups across postarrival time points.
|
Within 24 hours before departure; within 2 hours after arrival; 24 +/- 2 hours; and 48 +/- 2 hours after arrival. 3 days
