Insulin secretion decline in Walker-256 tumor-bearing rats is early, follows the course of cachexia, and is not improved by lixisenatide.

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
Lixisenatide, a glucagon-like peptide-1 receptor agonist, is used to stimulate insulin secretion in patients with type 2 diabetes mellitus. However, its effect on insulin secretion in cancer patients, particularly during the cachexia course, has not yet been evaluated. The purpose of this study was to investigate the lixisenatide effect on INS secretion decline during the cachexia course (2, 6, and 12 days of tumor) in pancreatic islets isolated from Walker-256 tumor-bearing rats. Pancreatic islets of healthy and tumor-bearing rats were incubated in the presence or absence of lixisenatide (10 nM). Tumor-bearing rats showed reduction of body weight and fat and muscle mass, characterizing the development of cachexia, as well as reduction of insulinemia and INS secretion stimulated by glucose (5.6, 8.3, 11.1, 16.7, and 20 mM) on days 2, 6, and/or 12 of tumor. Lixisenatide increased the 16.7 mM glucose-stimulated insulin secretion, but not by 5.6 mM glucose, in the islets of healthy rats, without changing the insulin intracellular content. However, lixisenatide did not prevent the decreased 16.7 mM glucose-stimulated insulin secretion in the pancreatic islets of rats with 2, 6, and 12 days of tumor and neither the decreased insulin intracellular content of rats with 12 days of tumor. In consistency, in vivo treatment with lixisenatide (50 μg kg
