Prognostic Value of Electroneuronography in Severe Cases of Facial Palsy.
Article in Annals of rehabilitation medicine, 2023. 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
objectiveTo examine the prognostic value of electroneuronography (ENoG) in predicting functional recovery in severe cases of acute facial palsy.
methodsPatients with severe degrees of facial palsy (initial House-Brackmann [HB] grades IV to VI) with available electrodiagnostic studies conducted 2-4 weeks after symptom onset were reviewed retrospectively. The patients were categorized into "good recovery" and "poor recovery" groups, with the former showing mild to no dysfunction (HB I to III) and the latter exhibiting moderate to severe dysfunction (HB IV to VI) on follow-up evaluation, 2 months after onset. ENoG amplitudes in four facial muscles (frontalis, nasalis, orbicularis oculi, and orbicularis oris), as well as age, sex, affected side, disease etiology, comorbidities, and laboratory findings, were compared between the two groups.
resultsThirty-seven patients were included. Twenty-nine of the patients showed "good recovery," and eight showed "poor recovery" at 2 months after symptom onset. Univariate analysis yielded no significant difference in age, sex, affected side, disease etiology, comorbidities, and laboratory findings between the two groups. Preserved ENoG amplitudes (individual, average, and trimmed means) were significantly higher in the good recovery group than in the poor recovery group (p<0.005). Sex (p=0.038) and the ENoG of the nasalis muscle, acquired 2-4 weeks from symptom onset (p=0.004), showed significant differences in multivariate regression analysis.
conclusionThis study suggests that the female sex and lower ENoG of the nasalis muscle, acquired 2-4 weeks from symptom onset, have negative prognostic value for the 2-month functional outcome of severe facial palsy cases.
