Effect of dietary medicinal plants on physiological responses of broiler chickens challenged with Campylobacter jejuni.
Article in Veterinary medicine and science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPhytogenic additives would be helpful to alleviate the adverse effect of Campylobacter jejuni on the performance and physiological responses of broiler chickens.
objectiveThis experiment was carried out to investigate the effects of Echinacea purpurea (EP) and Thymbra spicata (TS) on the performance, nutrient digestibility, serum biochemistry, intestinal morphology, intestinal microbiota and immune responses of broilers challenged with C. jejuni from 0 to 42 days of age.
methodsA total of 240 male broiler chickens were divided into 6 groups and fed various diets: a control diet; the control diet supplemented with EP at 0.25% (EP25) or 0.50% (EP50); the control diet supplemented with TS at 0.25% (TS25) and 0.50% (TS50); or the control diet containing erythromycin at 55 ppm. Chicks were orally challenged with C. jejuni on Days 21 and 23 of age.
resultsEP and TS25 diets enhanced European production efficiency factor, feed conversion ratio and digestibility of dry matter and organic matter. TS25 increased duodenal villous height (VH) and surface area on Day 42 of age. EP25 diet increased ileal VH compared to control and erythromycin diets. Diets containing certain EP25 and TS increased the Bifidobacterium population and decreased C. jejuni population on Day 39 of age. EP50 and TS50 diets increased antibody titration against Newcastle disease virus.
conclusionsIn conclusion, EP and TS dietary supplementation improved performance, microflora, intestinal morphology and immune responses in C. jejuni-challenged broilers.
