Benefit of a 2-Month Treatment with a Micronized, Purified Flavonoidic Fraction on Venous Ulcer Healing
Bibliographic record
Abstract
OBJECTIVE: To assess the efficacy of a micronized purified flavonoid fraction (Daflon 500 mg = Dios) in venous leg ulcer healing, in addition to compression therapy and standardized local care. DESIGN: Double-blind, multicentre, randomized, parallel groups, controlled versus placebo trial; stratification according to ulcer size. SUBJECTS: 107 patients, with venous ulcer of the leg for at least 3 months, and accepting bandaging therapy. RESULTS: 105 patients (Dios = 53, placebo = 52) were available for an intention to treat (ITT) analysis. Age (mean +/- SD, 71+/-11 years), gender (M = 33, F = 74) and ulcer size were evenly distributed among both groups. 99 patients completed the protocol (Dios = 51, placebo = 48). Among the 91 patients with ulcer size < or = 100 cm (Dios = 44, placebo = 47), a significantly higher number of patients had complete ulcer healing at 2 months in the Dios group (n = 14) in comparison to the placebo group (n = 6) after ITT analysis (32 vs. 13%, p = 0.028) and after per protocol analysis (32 vs. 14%, p = 0.048), and a shorter time duration of healing (p = 0.037). Among the 14 patients with ulcer size > 10 cm (Dios = 9, placebo = 5), no ulcer healed. CONCLUSION: This study showed that a 2-month course of purified micronized flavonoid fraction (2 tablets/day), in addition to conventional treatment, is of benefit in patients by accelerating complete healing of venous leg ulcers which are < or = 10 cm in diameter.

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.
