Maternal Extra Virgin Olive Oil Supplementation Enhances Offspring Immune Function: A Preclinical Study.
Article in International journal of molecular sciences, 2025. 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
Maternal diet influences offspring development, immune function, and intestinal health. This study investigates the effects of maternal supplementation with a key component of the Mediterranean Diet, extra virgin olive oil (EVOO), on the immune health of offspring at the end of lactation. Lewis rat dams received either refined olive oil (ROO), EVOO, or water (REF) during gestation and lactation. Plasma immunoglobulin G2c (IgG2c) concentration was elevated in pups born to EVOO-supplemented mothers, indicating enhanced immune development. Histological analysis of the small intestine revealed more goblet cells in the EVOO group, indicating a potential positive effect on the intestinal barrier function. In vitro assays showed that EVOO metabolites did not display cytotoxicity and had improved barrier integrity under a stress stimulus. These findings suggest that maternal EVOO supplementation may have beneficial effects on immune and intestinal development and health in offspring.
