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
introductionArteriovenous fistula (AVF) is the gold standard vascular access for hemodialysis (HD). A thrill or murmur immediately after creation of AVF is considered a predictive sign of success. However, this does not ensure final maturation for successful HD. Our objective was to determine different clinical and duplex parameters within AVF to predict maturation and subsequent successful HD. MATERIALS AND
methodsA prospective observational study was conducted on 187 patients who had AVF formation from July 2012 to May 2013. Following surgery, all patients had Doppler ultrasound (DU) on Days 0 and 7. Doppler parameters noted in the outflow vein were: Thrill, broadening of spectral waveform with increased peak systolic velocity (PSV) and spiral laminar flow (SLF). Patients with at least one positive parameter at Day 0 were followed-up serially and underwent repeat Doppler imaging on Day 7. Patients with the absence of all three parameters on Day 0 were excluded from the study. Endpoint was maturation of AVF, i.e. successful HD. Statistical analysis was performed with binary logistic regression, to find out the strongest and earliest predictor for maturation of AVF using SPSS version 20.
resultsSLF and broadening of spectral waveform with increased PSV were found to have a significant association with maturation (P = 0.0001). Presence of SLF on Day 0 most strongly predicted maturation. Presence of thrill or murmur could not predict the maturation.
conclusionsSLF pattern in AVF is the most important and the earliest predictor of maturation.
