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 LEW.1AR1-iddm rat is an animal model of human type 1 diabetes, which arose through a spontaneous mutation in the Dock8 gene within the MHC congenic background strain LEW.1AR1. This mutation not only mediates diabetes development but also leads to a variable T cell frequency in peripheral blood. In this study, the immune cell frequencies of primary and secondary lymphatic organs of LEW.1AR1-iddm rats were analysed at days 40 and 60 and compared to other MHC congenic LEW rat strains. In LEW.1AR1-iddm rats, the secondary lymphatic organs such as lymph nodes and spleen showed a reduced, around 15% in comparison to all other strains, but very variable T cell frequency, mirroring the fluctuating T cell content in blood. On the other hand, the frequency of B cells was increased by 10% in the lymph nodes and by 5% in the spleen. Thus, the decreasing number of T cells in blood could not be caused by an increase of T cells in secondary lymphatic organs. The frequency of single- or double-positive T cells in the thymus was unaffected. The T cell frequencies in the other analysed strains were more stable and mostly higher in all secondary lymphatic organs. Obviously, the Dock8 mutation leads to variabilities of T cell frequencies in blood as well as in secondary lymphatic organs. In conclusion, the Dock8 mutation was responsible for changed immune cell frequencies in different compartments and together with the RT1B/D
