Effects of Maternal and Cumulative Stress on Immune Phenotype and Stress Reactivity in Sows Later in Life.
Article in Animals : an open access journal from MDPI, 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
The timing and nature of gestational stress can alter offspring immune function and hypothalamic-pituitary-adrenal (HPA) axis regulation, yet the role of maternal stress history remains poorly understood. This study evaluated the effects of prenatal stress, maternal stress history, and repeated stress exposure on immune and stress reactivity in prenatally stressed (PS) gilts across two farrowings. Eleven PS second-parity sows (197.27 ± 19.22 kg) were sampled at multiple timepoints and compared with their maternally stressed (MS) dams. During the second pregnancy, PS sows received the same maternal treatment as their dams: placebo (CON) or hydrocortisone acetate (HCA) administered twice daily for 21 days during mid (M; d 51-72) or late (L; d 81-102) gestation. Data were analyzed using mixed models with repeated measures in SAS (Version 9.4). During the first pregnancy, PS gilts in the L-HCA group exhibited higher lymphocyte proliferation indices and plasma cortisol concentrations than MS dams (
