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

Amniotic epithelial cells (AECs) have immunomodulatory and anti-inflammatory properties that may improve outcomes in cell transplantation. However, their effect on islet engraftment after intraportal co-transplantation remains unclear. We evaluated the impact of co-transplanting syngeneic 600 islet equivalents (IEQs) with human AECs (hAECs) via the portal vein in a rat streptozotocin-induced diabetes model. The co-transplantation (Co-Tx) group showed normalization of blood glucose levels within 7 days after transplantation, sustained normoglycemia thereafter, and achieved a higher diabetes reversal rate than controls (100% vs. 71.4%, p < 0.01). Serum CXCL1 levels were significantly lower in the Co-Tx group indicating suppression of early inflammatory responses. Thrombin-antithrombin complex (TAT) levels also tended to be lower, raising the possibility of attenuation of the instant blood-mediated inflammatory reaction (IBMIR). In contrast, no significant differences were observed in VEGF levels or intrahepatic microvascular density. Co-transplantation with hAECs enhances islet engraftment likely through suppression of early inflammation, highlighting their potential as an adjunctive cellular therapy in islet transplantation.
