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
purposeTo compare the primary outcome of the radial artery deviation and reimplantation (RADAR) technique and the ultra-sound-guided percutaneous transluminal angioplasty (PTA) in the treatment of forearm arteriovenous fistula (AVF) type I stenosis in haemodialysis patients.
methodsA total of 35 patients with forearm AVF type I stenosis in our hospital were analyzed. The patients were divided into two groups: the RADAR group (n = 15), in which forearm AVF reconstruction was performed using the RADAR technique, and the PTA group (n = 20), where patients underwent ultrasound-guided PTA. Measurements including the AVF blood flow rate, the AVF resistance index, the vessel diameter at the site of stenosis, the vessel diameter of the AVF, and the primary patency of AVF were compared.
resultsThe two groups were comparable for the AVF blood flow rate, the AVF resistance index, the vessel diameter at the site of stenosis and the vessel diameter of the AVF both at pre-operation and post-operation. However, at 3 months after operation, the RADAR group has higher AVF blood flow rate, lower AVF resistance index, and larger vessel diameter at the site of stenosis than the PTA group. At 3 months after operation, the primary patency of AVF in the RADAR group and the PTA group was 93.33 and 55.00%, respectively.
conclusionAt 3 months after operation, the RADAR technique is associated with superior outcomes, suggesting RADAR may be an effective treatment option for patients with forearm AVF type I stenosis.
