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
The aim of this study was to identify the histological features of chicken enteroendocrine cells before and after hatching. Tissue samples from the duodenum, proximal and distal parts of the jejunum and ileum, cecum and colorectum were collected from the embryos at days 18, 19, 20, and 21 of incubation, and from 3-day-old chicks. The expression of glucagon-like peptide (GLP)-1, somatostatin (SST), and neurotensin (NT) in the enteroendocrine cells was detected using the streptavidin-biotin method, and the colocalization of these peptides was revealed using the double immunofluorescence method. All of assessed peptides were expressed in the enteroendocrine cells at day 18 of incubation. GLP-1-immunoreactive cells were only observed in the jejunum and ileum. The cell numbers gradually increased as incubation progressed. NT-immunoreactive cells were detected in all intestinal parts at all incubation days, and the highest expression was observed in the colorectum of 3-day-old chicks. SST-immunoreactive cells were observed from the duodenum to the ileum, excluding the colorectum. The double immunofluorescence method revealed that GLP-1 and NT colocalized in the same endocrine cells of the jejunum and ileum. The colocalization ratio of GLP-1 with NT was the highest in the distal ileum of 3-day-old chicks. However, neither GLP-1 nor NT colocalized with SST. These results indicate that chicken enteroendocrine cells markedly change their density and colocalization ratios before and after hatching.
