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

purposeDuring the Coronavirus disease 2019 (COVID-19) pandemic a reduction in the diagnosis of many otorhinolaryngological and audiological disorders has been widely reported. The main aim of this investigation was to evaluate the impact of COVID-19 outbreak on the incidence of acute hearing and vestibular disorders. MATERIALS AND

methodsA retrospective analysis was performed of all patients evaluated in an audiology tertiary referral centre for acute cochleo-vestibular impairment between March 1st 2020 and February 28th 2021 (Pandemic Year Period, PYP). Results were compared to patients presenting with the same disorders during two previous periods (March 1st 2019 to February 29th 2020 and March 1st 2018 to February 28th 2019; First Precedent Year Period, FPYP and Second Precedent Year Period, SPYP, respectively).

resultsThe annual incidence of total acute audio-vestibular disorders (number of annual diagnoses divided by total number of annual audiological evaluations) was 1.52% during the PYP, 1.31% in FPYP and 1.20% in SPYP. Comparison between the pandemic period and previous periods did not show a significant difference (p > 0.05). The overall incidence of SSNHL and combined acute cochlear-vestibular involvement was significantly higher during the PYP compared to the previous periods (p = 0.022).

conclusionsThere were no differences in the absolute number of acute audio-vestibular disorders during the pandemic compared to previous periods. Although not significant, the SSNHL during the pandemic appeared worse in terms of pure-tone average with a higher incidence of associated vestibular involvement. Further studies are needed to clarify the role of SARS-CoV-2 on audio-vestibular disorders incidence and pathophysiology.
