Lack of Tourniquet Effect of Below-Knee Stockings
Bibliographic record
Abstract
Objective: To determine whether below-knee compression stockings impede venous return by a tourniquet effect. Design: Randomised, cross-over clinical trial. Patients: Ten outpatient women suffering from mild or moderate primary varicose veins without skin trophic disorder. Methods: Air plethysmography with venous occlusion (50 mmHg) was used to measure arterial inflow (AI), venous volume (V50) and maximum venous outflow (MVO), without stockings and when wearing French class 1 (10-15 mmHg) and class 2 (15-20 mmHg) below-knee stockings. Results: No carry over due to the cross-over design was detected. There was no significant variation in MVO induced by class 1 (44 vs 45 ml/s) or class 2 (42 vs 41 ml/s) stockings. AI decreased significantly with class 2 (0.93 vs 1.22 ml/s, /? = 0.012) but not with class 1 (1.22 vs 1.20 ml/s) stockings. V50 did not change with class 1 (97 vs 95 ml) but decreased with class 2 (80 vs 98 ml, p = 0.031) stockings. Conclusion: No tourniquet effect of class 1 and class 2 below-knee stockings was observed. Venous capacity and arterial inflow were reduced by class 2 stockings.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
