[Temporary hyposmia in COVID-19 patients].
Article in HNO, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
backgroundThis is a report on the high incidence of olfactory dysfunction in COVID-19 patients in the first cohort of COVID-19 patients in Germany (Webasto cluster).
methodsLoss of sense of smell and/or taste was reported by 26 of 63 COVID-19 patients (41%), whereas only 31% of the patients experiencing hyposmia had simultaneous symptoms of rhinitis. Smell tests were performed in 14 of these patients and taste tests in 10. The measurements were conducted in a patient care setting in an early COVID-19 cohort.
resultsAn olfactory disorder was present in 10/14 patients, before as well as after nasal decongestion. In 2 of these patients, hyposmia was the leading or only symptom of SARS-CoV‑2 infection. All tested patients reported recovery of smell and/or taste within 8 to 23 days.
conclusionThe data imply that a) COVID-19 can lead to hyposmia in a relevant number of patients, the incidence was approximately 30% in this cohort; b) in most cases, the olfactory disturbance was not associated with nasal obstruction, thus indicating a possible neurogenic origin; and c) the olfactory disorder largely resolved within 1-3 weeks after the onset of COVID-19 symptoms. There were no indications of an increased incidence of dysgeusia. These early data may help in the interpretation of COVID-19-associated hyposmia as well as in the counseling of patients, given the temporary nature of hyposmia observed in this study. Furthermore, according to the current experience, hyposmia without rhinitic obstruction can be the leading or even the only symptom of a SARS-CoV‑2 infection.
