Oral Manifestations in the Post COVID-19 Condition: A Systematic Review With Meta-Analysis.
Synthesis in Reviews in medical virology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Post-COVID-19 condition, or Long COVID, is characterised by symptoms persisting or emerging beyond 12 weeks after acute infection. Among over 200 reported symptoms, oral manifestations such as taste loss and dry mouth have been identified. This systematic review reports the frequency and characteristics of these symptoms. Registered in PROSPERO and following PRISMA guidelines, the review included observational studies on COVID-19-positive adults presenting oral symptoms in the post-COVID-19 condition. A search in six databases (Medline/PubMed, Embase, Web of Science, Cochrane, SCOPUS, and LILACS) was conducted in January 2024. Risk of bias was assessed using Joanna Briggs Institute's critical appraisal tools, and certainty of evidence via GRADE. A meta-analysis using the inverse variance method estimated oral symptom prevalence. Of 4552 articles, 107 were included. Taste dysfunction persisted in 8% (95% CI 6%-10%) of patients beyond 12 weeks. Combined taste and smell alterations had a prevalence of 17% (95% CI 13%-21%). Less frequent symptoms included hyposalivation, periodontitis, mouth ulcers, tongue mucosal changes, facial tingling, sensitivity in the trigeminal nerve, difficulty swallowing, and lesions in the hard palate. Taste alterations were the most commonly reported symptom, underscoring the need for clinical recognition and appropriate management by oral health professionals. Additionally, the wide range of other oral manifestations highlights the necessity for further research to better understand their prevalence, underlying mechanisms, and clinical implications in post-COVID-19 patients.
