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
Background: Radio-cephalic arteriovenous fistula (RC-AVF) is regarded as favored choice for vascular access in patients undergoing hemodialysis. However, the mainstream surgical technique is associated with low primary patency rate. Recently, RC-AVF creation by modified no-touch technique (MNTT) is reported to increase primary patency and decrease juxta-anastomotic stenosis in initial small sample size and short-term follow-up study. This comparative study aims to investigate the hemodynamic discrepancies between RC-AVF created by MNTT and conventional technique (CT). Methods: To further explore the differences between MNTT and CT, four-dimensional (4D) flow magnetic resonance imaging (MRI) was used to analyze the hemodynamic of RC-AVFs. Thirty patients who underwent 4D-flow MRI examination were included. Eighteen in the MNTT group and twelve in the CT group. Hemodynamic analysis was performed to measure blood flow velocity, vorticity, relative helicity, wall shear stress (WSS) and oscillatory shear index (OSI) in the artery and vein of RC-AVFs created by the two techniques. Results: The averaged velocity, vorticity and WSS was found higher in the MNTT group (velocity =0.771±0.029 m/s in artery, 0.955±0.055 m/s in vein; vorticity =529.115±50.006 1/s in artery, 709.895±43.180 1/s in vein; WSS =7.885±0.239 Pa in artery, 9.378±0.738 Pa in vein) than those in the CT group (velocity: 0.577±0.011 m/s in artery, 0.611±0.014 m/s in vein; vorticity =438.028±6.819 1/s in artery, 539.670±19.891 1/s in vein; WSS =5.611±0.213 Pa in artery, 5.314±0.279 Pa in vein) (P<0.001). The averaged relative helicity magnitude of artery in MNTT group was higher than that CT group (0.349±0.067 Conclusions: Patients in the MNTT group had good prognosis related to the improved fistula hemodynamics.
