1 · What the graph read from it

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.

2 · The registry

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 association between Herpesviruses (HSV-1, HSV-2, VZV, EBV, CMV) and SARS-CoV-2 in the acute phase of Sudden Sensorineural Hearing Loss (SSNHL), correlating serological and PCR findings with clinical and audiometric outcomes.

methodsProspective cohort study including 53 patients evaluated between March 2020 and February 2024. Audiological assessment, serological testing (IgM and IgG), PCR for herpesviruses and SARS-CoV-2, and magnetic resonance imaging were performed.

resultsMost patients (90.6%) presented with unilateral hearing loss. Serological evidence of viral exposure was observed in 43.4% of cases, including SARS-CoV-2 (26.4%), HSV (22.6%), and CMV (5.6%). Coinfection with two viruses occurred in 11.3% of patients and was associated with poorer hearing outcomes (p = 0.0032). Bilateral hearing loss (9.4%) was also associated with no improvement (p = 0.0368). In multivariate analysis, COVID-19 infection remained independently associated with poorer outcomes.

conclusionSSNHL was associated with a high frequency of viral serological markers. Viral coinfection may be associated with poorer prognosis, although causality cannot be established. Initial hearing loss severity and bilateral involvement remained important prognostic factors. Serological findings may serve as complementary tools for clinical characterization and prognostic assessment, although their etiological role remains uncertain. LEVEL OF EVIDENCE: 2:
