Shorter Digestion Times of Donor Islets Is Associated With Better Islet Graft Function After Islet Transplantation.
Article in Cell transplantation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Although islet transplantation is effective in reducing severe hypoglycemia events and controlling blood glucose in patients with type 1 diabetes, maintaining islet graft function long-term is a significant challenge. Islets from multiple donors are often needed to achieve insulin independence, and even then, islet function can decline over time when metabolic demand exceeds islet mass/insulin secretory capacity. We previously developed a method that calculated the islet graft function index (GFI) and a patient's predicted insulin requirement (PIR) using mathematical nonlinear regression. Both PIR and GFI could be used by physicians as tools to monitor islet graft function and to guide supplementing the patient with exogenous insulin to prevent beta-cell exhaustion. This study investigates the factors relating to the islet preparation process, as well as donor and recipient characteristics, and assessed their associations with PIR and GFI after transplantation. The goal is to determine the most relevant factors that influence islet graft function after transplantation. We examined the effects of donor and recipient characteristics, and islet processing factors on posttransplanted PIR and GFI. The PIR and GFI at 3 months were calculated using patients' baseline insulin intake, posttransplant 2-h postprandial blood glucose, and glucagon-stimulated C-peptide. Thirteen transplants that resulted in progressive decline in patients' weekly averaged insulin intake over the initial weeks after transplant (assuming constant glucose level) with available 3-month PIR and GFI data were chosen for the investigation. Univariate analyses were performed to assess the effects of donor and recipient characteristics and islet processing factors on islet graft function as reflected by PIR and GFI. The PIR and GFI were treated as continuous response variables in separate linear regression models. Shorter digestion time of isolated donor islets were associated with lower PIR (
