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
Purpose: To evaluate the diagnostic quality and detection of anatomical variants in branching patterns of the renal arteries for non-contrast quiescent-interval slice-selective (QISS) MR Angiography (MRA) compared to CT Angiography (CTA). Methods: Patients who underwent a QISS MRA of the renal arteries as well as CTA as reference standard were included in this retrospective study. Signal-to-noise ratio (SNR), contrast-to-noise ratio (SNR), and vessel diameter were determined in the left and right renal arterial systems. Image quality and diagnostic confidence were assessed with a standardized five-point Likert scale. Sensitivity, specificity and accuracy for the detection of anatomical variants in branching patterns (accessory renal artery, aberrant renal artery and early branching) of the renal arterial system were determined compared to CTA as reference standard. Results: 30 patients (59 renal arteries) were included in this retrospective study. CTA reached significantly higher median SNR compared to QISS MRA (10.96, inter-quartile range (IQR) 6.70-16.11 vs. 5.65, IQR 4.38-8.76, respectively, p < 0.001). Median CNR was significantly higher in QISS MRA (16.75, IQR 13.09-20.96) compared to CTA (13.22, IQR 7.49-18.57), p = 0.006. Diameters of the renal arteries were similar between QISS MRA and CTA (5.8 mm, IQR 4.90-6.60 versus 5.8 mm, IQR 4.75, 6.70, p = 0.893). Diagnostic confidence was rated excellent for both, though significantly higher for CTA (5, IQR 5-5,) compared to QISS MRA (5, IQR 4-5), p = 0.003). 19 of 20 variants in branching pattern could be detected successfully by QISS. Conclusion: QISS MRA offers similar diagnostic confidence and image quality to CTA as reference standard. Further, QISS MRA demonstrates excellent diagnostic accuracy in detecting anatomical variants of branching patterns of the renal arterial vasculature.
