1 · What the graph read from it

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.

2 · The registry

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

backgroundHuman chorionic gonadotropin (hCG) is a glycoprotein hormone critical for reproduction, particularly in pregnancy maintenance and fertility treatments. Beyond reproduction, hCG may influence immune regulation, cancer biology, and neurological processes.

objectiveThis review critically examines the current evidence regarding the potential neurological effects of hCG, synthesizing findings from experimental and clinical studies to assess its proposed roles in neuroinflammation, oxidative stress, and blood-brain barrier modulation.

resultDysregulated hCG levels-arising from pregnancy complications, assisted reproductive technologies (ART), or hCG-secreting tumors-have been associated with markers of neurotoxicity, including neuroinflammation, oxidative stress, and altered blood-brain barrier integrity. Evidence remains largely associative, and causal mechanisms linking hCG to neurobiological vulnerability are not yet established. Proposed pathways include modulation of immune cell activity, neurotransmitter signaling, and endothelial function.

conclusionhCG exhibits a dual nature: essential for reproduction and immune adaptation, yet potentially neurotoxic under dysregulated conditions. This review synthesizes mechanistic hypotheses, highlights knowledge gaps, and underscores the need for rigorous longitudinal and experimental studies to clarify hCG's impact on the nervous system.
