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

objectivesOlfactory and gustatory dysfunction (OD/GD) are now recognized as typical symptoms of COVID-19 infection. However, their pathogenesis remains unclear and no clear prognostic factors have been identified. We have analyzed a cohort of mild/moderate hospitalized patients to identify possible clinical or immunological predictors of recovery from OD/GD.

methodsClinical and biological parameters were reviewed along with associated comorbidities. Chemosensory Complaint Score was administered on admission and 30 days after the first negative swab. Unpaired Wilcoxon and chi-squared tests were used to compare the variables in the patients who recovered versus those who did not.

resultsFrom a cohort of 119 hospitalized patients, 43 (36%) reported OD/GD on admission. 60.6% had a full recovery from OD and 69.2% from GD. Only the concentration of IL-10 on admission emerged as significantly associated with recovery of taste (p = 0.041) while allergic respiratory disease was more prevalent in the group who did not recover from OD (p = 0.049) and GD (p = 0.007).

conclusionThese findings suggest that COVID-19 associated OD/GD is an inflammatory-mediated condition and that clinical and immunological parameters could predict the evolution of these symptoms.
