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
backgroundDiabetes is a condition characterized by a loss of pancreatic β-cell function, which results in the dysregulation of insulin homeostasis. Using a partial pancreatectomy model in axolotl, we aimed to observe the pancreatic response to injury.
resultsHere we show a comprehensive histological characterization of pancreatic islets in axolotl. Following pancreatic injury, no apparent blastema-like structure was observed. We found a significant, organ-wide increase in cellular proliferation post-resection in the pancreas compared to sham-operated controls. This proliferative response was most robust at the site of injury. Further, an increase in nuclear density was observed, suggesting compensatory congestion as a mechanism of regeneration. We found that β-cells actively contributed to the increased rates of proliferation upon injury. β-Cell proliferation manifested in increased β-cell mass in injured tissue at 2 weeks post-injury. At 4 weeks post-injury, we found organ-wide proliferation to be extinguished while proliferation at the injury site persisted, corresponding to pancreatic tissue recovery. Similarly, total β-cell mass was comparable to sham after 4 weeks.
conclusionsOur findings suggest a non-blastema-mediated regeneration process takes place in the pancreas, by which pancreatic resection induces whole-organ β-cell proliferation without the formation of a blastemal structure. This process is analogous to other models of compensatory congestion in axolotl.
