Breed- and age-associated variation in hematological parameters and Toll-like receptor 2 gene expression in peripheral blood mononuclear cells of commercial and purebred laying hens during the laying cycle.
Article in Veterinary world, 2026. 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
Background and Aim: Hematological parameters and innate immune responses are influenced by genetic background and physiological status, making them valuable indicators of health and immune competence in laying hens. However, comparative information on breed- and age-related variation in hematological characteristics and Materials and Methods: Twenty clinically healthy laying hens (n = 5 per breed × age group) comprising LB and WL breeds at 42 and 80 weeks of age were maintained under identical management conditions. Blood samples were collected for hematological analysis and PBMC isolation. Hematological parameters were determined using standard laboratory methods, whereas Results: Breed significantly affected hemoglobin concentration, lymphocyte percentage, heterophil-to-lymphocyte (H:L) ratio, and Conclusion: Breed and physiological stage significantly influence hematological characteristics and
