Secretin and pancreatic islet blood flow in anesthetized rats: increased insulin secretion with no augmentation of blood perfusion.

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
Secretin is a stimulator of both endocrine and exocrine secretions of the pancreas, and we aimed to evaluate its effects on splanchnic blood flow in rats with a microsphere technique. Anesthetized rats were infused with secretin (0.5 or 2.0 micrograms/kg body weight/hr) for 10 minutes. Some animals were normoglycemic, whereas other received a glucose injection 3 minutes before blood flow measurements. Secretin did not affect serum insulin concentrations in normoglycemic animals but consistently led to higher insulin concentrations in the hyperglycemic rats. Total pancreatic blood flow was increased by the highest secretin dose in normoglycemic animals, whereas no effects were seen in the hyperglycemic rats. Administration of glucose caused a pronounced increase in islet and fractional islet blood flow in saline-infused animals. Secretin affected neither islet nor fractional blood flow in normoglycemic or hyperglycemic rats. Glucose administration increased duodenal blood flow in animals infused with saline and both duodenal and colonic blood flow in rats given the lowest dose of secretin. No effects on either colonic or duodenal blood perfusion were seen in animals infused with the highest dose of secretin. Secretin mainly affects blood flow to the whole pancreas and not that of the islets. Furthermore, glucose-induced insulin release can be achieved without a simultaneous increase in islet blood flow; that is these two events may be dissociated from one another.
