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
Introduction: Evidence suggests that gestational exposure to Lipopolysaccharide (LPS) results in fetal zinc deficiency and eventually neurodevelopmental abnormalities. In this study, we utilized a rat model of Maternal Immune Activation (MIA) to investigate the possible neuroprotective effects of zinc supplementation during pregnancy on hippocampal astrocytes activation as well as inflammatory cytokines expression in adult offspring. Methods: Pregnant rats received intraperitoneal injections of either LPS (0.5 mg/kg) or saline on Gestational Days (GD) 15 and 16, and orally gavaged with zinc sulfate (30 mg/kg) during pregnancy. Astrocyte density and histological assessment were evaluated in the hippocampus of adult offspring on Postnatal Days (PND) 60 to 62. Also, the mRNA levels of Results: Prenatal exposure to LPS resulted in upregulated expression levels of Conclusion: This study supports the premise that zinc supplementation during pregnancy might be an early treatment option to inhibit hippocampal inflammation induced by the maternal immune response to infectious agents. Highlights: Maternal immune activation induced mild hippocampal inflammation in adult offspring.Zinc supplementation suppressed LPS-induced hippocampal inflammation in offspring.Zinc might be an early therapeutic option to inhibit neurodevelopmental impairments. Plain Language Summary: Schizophrenia is a chronic and disabling psychiatric disorder, affecting an estimated one percent of the world's population. To date, the biological mechanisms underlying this mental disorder remain largely elusive, however, research has demonstrated the involvement of both genetic and environmental factors. Of environmental factors, gestational exposure to rubella, influenza, and genital-reproductive infections have gained particular interest among researchers. Based on this evidence, in the present study, we used an animal model of schizophrenia and showed the beneficial effect of zinc supplementation during pregnancy to protect against LPS-induced inflammation in the hippocampus of adult offspring. Collectively, our study provides support for the premise that early treatment might be a suitable option to prevent schizophrenia risk in progeny.
