Gene Variants Associated With Individual Sensitivity for Taste Changes After the COVID-19 Infection.
Article in BioMed research international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Human gustatory function is a complex trait combining taste, smell, and touch required for the safety and quality assessment of ingested food. Taste dysfunction is one of the most prominent symptoms of COVID-19 that was reversible in most cases, but some patients reported permanent changes in their perception of different food sources. This symptom brought attention to the complexity of the regulation of smell and taste and their potential use in diagnostics and treatment of acute and chronic taste disorders. We investigated the genetic association of candidate genes with SARS-CoV-2 infection-related dysgeusia. A total of 96 individuals with confirmed virus infection were divided into groups according to the presence of self-reported taste dysfunction and genotyped using a custom Illumina gene panel. Out of 18 functionally related taste genes, statistically significant differences were observed for HCN4 variants c∗2393C > G (p = 0.013) and c.2556G > A (p = 0.026), PLCB2 variants c.3037-55T > C (p = 0.019) and c.582+958_582+959inv (p = 0.021), and TAS1R1 variant c.1594+41G > A (p = 0.03), which indicate possible association to taste dysfunction in response to virus infection.
