The other Babinski sign in Hemifacial Spasm: a clinical marker of severity and its predictive association with η-like vA-PICA compression.
Observational study in Annals of medicine, 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
objectiveTo investigate the clinical significance of the other Babinski sign in hemifacial spasm (HFS), focusing on its association with symptom severity and specific neurovascular compression (NVC) patterns.
methodsThis prospective observational study evaluated 69 consecutive HFS patients undergoing microvascular decompression. The association between the other Babinski sign and HSGS scores was assessed using the chi-square test for independence, with Cramer's V quantifying association strength. Subsequently, univariate and multivariate logistic regression analyses were performed to identify NVC patterns predictive of the other Babinski sign.
resultsThe other Babinski sign was present in 15/69 (21.7%) patients. Its presence was significantly associated with higher HSGS scores (
conclusionThe other Babinski sign is a significant clinical indicator of more severe HFS and is strongly associated with the η-like VA-PICA compression pattern. This sign may aid in preoperative assessment by predicting HFS severity and specific underlying vascular NVC morphologies, potentially informing surgical strategy.
