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
purposeSudden hearing loss (SHL) complaints constitute a substantial proportion of admissions to audiology clinics; however, data on individuals presenting with suspected SHL prior to diagnosis remain limited. This study aimed to describe the audiologic findings and symptoms of adult patients referred to our clinic with suspected SHL.
methodsMedical records of patients referred with suspected SHL between January 2018 and December 2019 were retrospectively reviewed. A total of 106 participants (108 ears) were included. Participants were classified into four groups based on audiologic findings, and intergroup comparisons were conducted. Logistic regression analysis was used to identify variables most strongly associated with SHL diagnosis.
resultsThe mean duration of hearing loss complaint was 8.8 days (SD = 8.8), and the mean pure-tone average (PTA) was 31.4 dB HL (SD = 19.9). Two participants (1.9%) had bilateral involvement, and 28.7% met the diagnostic criteria for SHL. The most frequently reported symptoms were tinnitus (63%) and ear fullness (42.6%). Logistic regression analysis indicated that the overall model was statistically significant (p < 0.001). Of all predictors, only the speech discrimination score (SDS) was independently associated with diagnosis (p < 0.05).
conclusionThe logistic regression model effectively differentiated individuals with and without SHL. Nearly half of the patients presenting with suspected SHL had normal hearing (45.4%), and 14.8% demonstrated findings consistent with middle ear pathology. These results highlight the substantial clinical burden associated with suspected SHL referrals and suggest that the coexistence of multiple symptoms may complicate the diagnostic process.
