A Clinical Comparison of Pycnogenol, Antistax, and Stocking in Chronic Venous Insufficiency.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This 8-week registry study was a comparative evaluation of Pycnogenol (French Maritime Pine Bark extract; Horphag Research, Geneva) and Antistax (grape leaf extract [GLE, Boehringer Ingelheim, Germany]) in controlling symptoms of chronic venous insufficiency (CVI). "Standard management" for CVI is compression; a group of comparable subjects was monitored to evaluate the effects of stockings. The registry included 183 patients (166 completing). Supplementation with Antistax (two tablets of 360 mg/d) or Pycnogenol (100 mg/d) was used. The groups were comparable for age, symptoms, venous incompetence, and microcirculation (with increased capillary filtration and skin flux) at inclusion. At 8 weeks, the rate of swelling (p < 0.05) and skin flux decreased toward normal values; changes were more important with Pycnogenol (p < 0.05). Transcutaneous Po 2 was increased more with Pycnogenol (p < 0.05). Ankle circumference was decreased more (p < 0.05) with Pycnogenol. An analog scale quantified symptoms. At 8 weeks, pain and edema were decreased with Pycnogenol and elastic compression (p < 0.05) with prevalence for Pycnogenol (p < 0.05). Edema with Pycnogenol was decreased by 40%. Induration was reduced only in the Pycnogenol group (p < 0.05) with minimal variations in the other groups. Tolerability and compliance were optimal. Elastic compression was correctly used by 80% of the patients indicating that it may be more difficult to use, particularly in warmer days. Costs for Pycnogenol were lower (96; 3.3 Euros) in comparison with the other groups (132;1.4 Euros for GLE and 149; 2.2 Euros for compression).
