Enhancement of Subcutaneous Islet Transplant Performance by Collagen 1 Gel.
Article in Cell transplantation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Human islets can be transplanted into the portal vein for T1 diabetes, and a similar procedure is being used in a clinical trial for stem cell-derived beta-like cells. Efforts have been underway to find an alternative transplant site that will foster better islet cell survival and function. Although conceptually attractive, the subcutaneous (SC) site has yielded disappointing results, in spite of some improvements resulting from more attention paid to vascularization and differentiation factors, including collagen. We developed a method to transplant rat islets in a disk of type 1 collagen gel and found improved efficacy of these transplants. Survival of islets following transplantation (tx) was determined by comparing insulin content of the graft to that of the pre-transplant islets from the same isolation. At 14 days after transplantation, grafts of the disks had more than double the recovered insulin than islets transplanted in ungelled collagen. SC grafts of disks had similar insulin content to grafts in a kidney site and in epididymal fat pads.
