Research Note: Effect of age on the distribution of lymphocytes in the oviduct in Turkey breeder hens.
Article in Poultry science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Considering the lack of research on the local immunity of the reproductive tract in other poultry species than chickens, the aim of this study was to determine the contribution of T and B cell subpopulations in different parts of breeder turkey oviduct mucous membrane with the use of flow cytometry. In addition, the study aimed to establish an impact of bird age and different stages of the egg production cycle on the systemic and local oviduct-related immune system structure. Our study results demonstrated a lower percentage of T lymphocytes in 32-wk turkey hens followed by a successively increasing population of these cells up to the 38th week of bird's life. The results of our study have also shown a similar dependency between birds' age and number of B lymphocytes. In addition, we demonstrated a decrease in the number of immune system cells in the oviduct, blood, and spleen of turkey hens in the late and end laying period. The differences reported in the number of lymphocyte subpopulations in the reproductive system of laying turkey hens at various stages of the production cycle may, to some extent, explain the frequency and periods of increased predilection to the incidence of infectious diseases in birds under field conditions.
