Hens and roosters of two distinct lines differ in immune cell profiles.
Article in Poultry science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sexual dimorphism in immune function influences disease susceptibility, yet sex-specific immune characteristics in chickens remain poorly understood, particularly across genetically divergent lines. This study investigated sex- and line-dependent differences in the peripheral and lymphatic immune system in lines selected for high and low feather pecking. Immune cell subsets were quantified in blood, spleen and cecal tonsils, and functional immune parameters were analyzed by measuring plasma antibody concentration and mitogen-induced lymphocyte proliferation capacity. Distinct immunological differences were observed between roosters and hens, as well as between lines, with several effects being tissue- and sex-specific. The higher overall numbers of immune cells observed in the spleen of roosters were primarily attributable to their larger organ mass, whereas in the cecal tonsils this was mainly due to a higher cell density. Roosters had fewer peripheral B cells, lower antibody concentrations and B lymphocyte proliferation capacity, along with fewer CD4
