Association Between High Jugular Bulb and Sudden Sensorineural Hearing Loss: A Computed Tomography Based Study.
Article in International journal of general 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
Objective: To explore the correlation between high jugular bulb (HJB) and sudden sensorineural hearing loss (SSNHL) by collecting and analyzing data from patients diagnosed with sudden sensorineural hearing loss (SSNHL) accompanied by HJB. Methods: A total of 62 patients with acute deafness admitted to the Otolaryngology ward of the First Affiliated Hospital of Anhui University of Chinese Medicine from October 2023 to June 2024 were included. Criteria were based on HJB reaching or exceeding the cochlear base. Patients were divided into two groups based on the presence of HJB. Both groups underwent thin-slice CT, pure tone threshold testing, and a tinnitus questionnaire. Age, sex, affected side, jugular bulb height, tinnitus handicap inventory (THI) score, and pure tone average (PTA) before and after treatment were recorded. The impact of these parameters on hearing loss and prognosis was analyzed, focusing on whether the elevation degree of the jugular bulb affected outcomes in sudden sensorineural hearing loss (SSNHL). Results: Before treatment, no statistically significant difference in average hearing threshold was found between the two groups (P>0.05). After treatment, both groups showed decreased average hearing thresholds (P<0.05), but the non-HJB group had significantly better improvement (P<0.01). Pre-treatment THI scores in the HJB group were significantly higher than in the non-HJB group (P<0.01). Post-treatment THI scores improved in both groups (P<0.05), with the non-HJB group showing significantly better outcomes (P<0.01). The effective treatment rate for patients with mild HJB (64.7%) was higher than those with severe HJB (42.9%), though not statistically significant (P>0.05). In the HJB group, admission and discharge PTA and THI scores were positively correlated with HJB values (P<0.05). Conclusion: Sudden sensorineural hearing loss (SSNHL) patients with high jugular bulb tend to have poorer hearing recovery and worse tinnitus outcomes compared to those without HJB.
