Immune Responses to Live-Attenuated Prime-Boost Vaccination Are Independent of Injection Site in Calves.
Article in Microbiology and immunology, 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
Vaccination is highly effective in controlling infectious diseases in calves. A prime-boost injection is often administered intramuscularly in the neck and the hip in calves. However, no guidelines have established whether the same vaccination sites could be used for booster vaccinations. This study investigated the influence of intramuscular administration sites for sequential vaccines on immune responses in calves. All calves received the primary live-attenuated viral vaccine into the left side of the neck. Four weeks later, the booster was administered at the same site as the primary vaccine (local boost group) or in the right hip (distal boost group). The neutralizing antibody titers did not differ significantly between the groups. To assess T-cell responses to viral antigens after booster vaccination, the expression levels of lymphocyte activation markers CD25 and CD69 were measured in peripheral blood mononuclear cells (PBMCs). The site of booster administration had no significant effect on the activation of CD4
