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

backgroundSuccessful pancreas transplantation requires surgical expertise and multidisciplinary medical management. The impact of transplant center volume on pancreas allograft survival remains unclear.

methodsWe examined Organ Procurement and Transplantation Network data on 11 568 simultaneous pancreas-kidney (SPK) and 4308 solitary pancreas (pancreas transplant alone and pancreas after kidney) transplants between 2000 and 2013.

resultsAverage annual transplant center volume was categorized by tertiles into low, medium, and high volume, respectively, as follows: 1 to 6 (n = 3861), 7 to 13 (n = 3891), and 14 to 34 (n = 3888) for SPK, and 1 to 3 (n = 1417), 4 to 10 (n = 1518), and 11 to 33 (n = 1377) for solitary pancreas transplants. Favorable donor characteristics were seen in low-volume centers. For SPK transplantation, low (adjusted hazard ration [aHR], 1.55, 95% confidence interval [CI], 1.34-1.8) and medium (aHR, 1.24; 95% CI, 1.07-1.44) center volumes were associated with a higher risk of early pancreas graft failure at 3 months. The increased risk associated with low center volume extended to 1, 5, and 10 years. For solitary pancreas transplants, low, but not medium, center volume was associated with a higher risk of early pancreas graft failure at 3 months (aHR, 1.56; 95% CI, 1.232-1.976), and this risk persisted over 10 years. Patients transplanted at high-volume centers had better pancreas survival rates across all categories of the Pancreas Donor Risk Index.

conclusionOn average, low center volume were associated with higher risk for pancreas failure. Future studies should seek to identify care processes that support optimal outcomes after pancreas transplantation irrespective of center volume.
