Characteristics and prognostic assessment of acute low-frequency sensorineural hearing loss: a retrospective analysis of 546 cases.

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
BACKGROUND/
objectivesThe incidence of acute low-frequency hearing loss has gradually increased in recent years. However, its specific etiology and pathophysiology remain largely unclear. Therefore, the aim of this study was to investigate the prognostic factors of acute low-frequency sensorineural hearing loss. PATIENTS AND
methodsPatients were grouped based on post-treatment pure-tone hearing thresholds: complete, marked, and slight recovery, or no change. We analyzed correlations between prognosis and age, sex, affected side, pathogenesis, underlying diseases, onset days, dizziness, degree of hearing loss, vestibular function, electrocochleography results, and gadolinium-enhanced inner ear MRI. Correlational analyses were completed using univariate and multivariate logistic regression. A
resultsOverall 546 patients with acute low-frequency sensorineural hearing loss were included. Univariate analysis revealed significant differences among groups regarding age, onset days, degree of hearing loss, cochlear hydrops on gadolinium-enhanced inner ear magnetic resonance imaging, and abnormal electrocochleography (all
conclusionsAdvancing age, abnormal electrocochleography, and degree of hearing loss were independently associated with poor prognosis of ALHL . With further study, these results could drive the development of improved clinical diagnostic guidelines to ultimately impact patient outcomes.
