1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the feasibility and repeatability of four-dimensional (4D) flow MRI for quantifying hepatic arterial blood flow (HABF) in healthy volunteers and patients with liver disease, and to identify sources of measurement variability. MATERIALS AND

methodsIn this prospective single-centre study, 23 healthy volunteers and 12 patients underwent two-dimensional (2D) and 4D flow acquisitions at 3T. Time-averaged and peak systolic vessel areas, velocities, and flow rates of the common hepatic artery (CHA) were extracted. Feasibility of 4D flow was assessed via CHA visibility on phase-contrast MRA. Scan-rescan repeatability of 4D flow was assessed by calculating within-subject coefficient of variation (CV

resultsAverage 4D flow feasibility rate was 83%. CV DISCUSSION: 4D flow MRI enables HABF quantification, though substantial scan-rescan variability exists. Acquisition-related factors were the main source of within-subject variability, while plane positioning contributed less.
