Prophylactically Decontaminating Human Islet Product for Safe Clinical Application: Effective and Potent Method.
Article in Transplantation direct, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundTransplanting pancreatic islets into recipients must be safe and effective to treat Type 1 diabetes. Islet quality and quantity are important, however, the final product must also be free from microbial contamination and low endotoxin levels.
methodsThis study explored a method to eliminate contamination in manufacturing islets for transplantation. A simple (single antibiotic, n=164) and refined (triple antimicrobial agents, n=279) pancreas decontaminating methods were used to test their effects on reducing the contamination rates in the islet final product. A total of 443 pancreata were processed for islet isolations. Three samples for microbial tests (Gram stain, aerobic, and anaerobic culture) were taken at pre-process (pancreas preservation), post-isolation, and post-culture. Endotoxin levels were measured only for islets considered for transplantation.
resultsOut of 443 pancreata used for islet isolation, 79 (17.8%) showed signs of contamination in pre-process samples; 10 (2.3%) were contaminated in both pre-process and in the final product (post-isolation and post-culture) samples. Contamination rates in which pre-process and final product samples were positive for contamination was significantly lower using the refined method (refined vs. simple method: 5% vs. 20.5%, p=0.045). Identical microbial species were present in both pre-process and in the final product.
conclusionsThis study demonstrated that the refined method reduces the rate of contamination of the islet final product and is safe for clinical application. Moreover, it may be used as a standard method during human islet manufacturing facilitating the application of a biological license agreement from United States Food and Drug Administration.
