Geraniin Ameliorates Haloperidol-Induced Orofacial Dyskinesia in Rats Through Mitigating Neuronal Oxidative Stress, Neuroinflammation, and Apoptosis via Modulation of the Nrf2 Signaling Pathway.
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. Cited by 3 papers.
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
Geraniin (GRN), an ellagitannin from Phyllanthus urinaria, shows antioxidant, anti-inflammatory, and neuroprotective effects. This study evaluated GRN's potential against haloperidol (HPD)-induced orofacial dyskinesia (OD). Rats treated with HPD (1 mg/kg i.p.) for 21 days exhibited dopamine D2 receptor blockade, neurotoxicity, and OD, characterized by vacuous chewing movements (VCM) and tongue protrusion (TP). Then, 60 min post-HPD, GRN was administered i.p. daily for 21 days. OD behaviors were assessed, and on Day 21, striatal tissues were analyzed for oxidative stress, mitochondrial function, inflammation, and apoptosis. GRN alone did not cause OD but significantly reduced HPD-induced VCM and TP. It also reduced oxidative stress, improved antioxidant defense, preserved mitochondrial function, and decreased neuroinflammation and apoptosis. These effects were blocked by ML385, a nuclear factor erythroid-2-related factor 2 (Nrf2) pathway inhibitor. GRN protects against HPD-induced OD, likely via Nrf2 activation. It may be a promising candidate for TD therapy, pending further clinical investigation.
