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

Vascular thrombosis is a major complication after pancreas transplantation. Because delays in detecting thrombosis often result in graft failure, monitoring blood flow is crucial. Periodic evaluation using color Doppler ultrasonography is mostly performed for monitoring blood flow in the grafted pancreas. However, conventional color Doppler imaging has limited capability to visualize low-velocity blood flow. Superb microvascular imaging (SMI) is a novel ultrasound Doppler technique that is especially sensitive in detecting low-velocity flow. Herein, the authors describe the utility of SMI for monitoring splenic venous blood flow not detected by conventional color Doppler ultrasonography after pancreas transplantation. Ultrasonographic evaluation was performed every 4-6 h for 2 weeks after pancreas transplantation. SMI was used for detecting venous blood flow that was not clearly visible by conventional color Doppler imaging. The greater part of venous blood flow was undetectable by conventional color Doppler imaging, especially in the horizontal regions of the splenic vein. However, SMI clearly described venous flow at all points, even immediately after transplantation and when the patient developed hypotension due to massive bleeding complications. SMI is an extremely useful tool for monitoring venous flow after pancreas transplantation and does not require contrast agents.
