Factors associated with loss and recovery of smell and taste after COVID-19 infection.
Article in Laryngoscope investigative otolaryngology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: To identify predictors associated with loss and recovery of smell and taste after COVID-19 infection. Methods: The Integrated Public Use Microdata Series (IPUMS) 2021 National Health Interview Series (NHIS) database was used to analyze factors associated with loss and recovery of smell and taste in respondents who had a previous COVID-19 infection. Significant variables from univariate analysis were included in a stepwise backward regression model to identify independent predictors. Results: Of the 3844 individuals who answered yes to having contracted COVID-19, 51.1% and 48.9% reported losing smell and taste, respectively. 95.7% recovered smell and 97% recovered taste. Predictors associated with higher odds of reporting a loss of smell included younger age (odds ratio [OR] 0.98; 95% confidence interval [CI] 0.98-0.99), female sex (OR 1.38; CI 1.17-1.63), use of e-cigarettes (OR 1.59; CI 1.25-2.02), and Mexican ethnicity (OR 1.61; CI 1.22-2.11). Predictors of taste loss were younger age (OR 0.98; CI 0.98-0.99), female sex (OR 1.31; CI 1.08-1.58), and higher BMI (OR 1.02; CI 1.00-1.04). Female sex was associated with decreased odds of reporting a recovery of smell (OR 0.74; CI 0.59-0.92) and taste (OR 0.54; CI 0.42-0.69). Black/African American race (OR 1.44; CI 1.03-2.03) and non-Mexican Hispanic ethnicities (OR 1.55; CI 1.02-2.34) were associated with an increased likelihood of reporting the recovery of smell. Conclusion: Various factors may be associated with the loss and recovery of smell and taste after COVID-19 infections. Clinicians may use this information to better counsel patients with these symptoms. Level of evidence: 4.
