Use of enoxaparin to diminish the incidence of vascular access stenosis/thrombosis in chronic hemodialysis patients.

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
backgroundEnoxaparin, a low molecular weight heparin, has been shown to be a safe and effective anticoagulant to prevent clotting in the extracorporeal circulation during hemodialysis. Enoxaparin also possesses antiproliferative properties, and reduces neointimal proliferation following vascular injury in animals. Use of enoxaparin during hemodialysis may be associated with decreased myointimal proliferation and diminished vascular access stenosis or failure.
aimThe aim of our study was to test the efficacy of enoxaparin to reduce the incidence of recurrent vascular access stenosis in chronic hemodialysis patients.
methodsTwenty-nine hemodialysis patients who suffered from recurrent arteriovenous (A-V) access stenosis were studied retrospectively to compare the incidence of vascular access procedures before and during enoxaparin administration. Enoxaparin was administered intravenously as a single bolus at the start of hemodialysis.
resultsTwenty-eight patients (14 male) were analyzed. Ten required a new fistula during the study period. Observed treatment times (years/patient) were 1.20 ± 0.87 for unfractionated heparin (UFH) and 3.04 ± 2.19 for enoxaparin (P = 0.0001). Angiographic procedure rates (procedures/year) were 1.76 ± 0.92 in the UFH group and 1.30 ± 1.01 in the enoxoparin group (P = 0.0786). There were no significant differences in time to first stenosis between the two groups (P = 0.5315). One patient receiving enoxaparin developed upper gastrointestinal bleeding and a second patient sustained a subdural hematoma after a fall.
conclusionOur study demonstrated a trend toward a decreased number of angiographic procedures for maintaining A-V access patency in selected chronic hemodialysis patients treated with enoxaparin in comparison with UFH as anticoagulant during dialysis.
