Xerostomia in survivors of severe COVID-19: findings from a Latin American cohort.
Article in Frontiers in oral health, 2025. 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
Objectives: SARS-CoV-2 primary affects the respiratory tract; however, evidence suggests the oral cavity can be involved in severe COVID-19 survivors. This study investigates factors associated with xerostomia in severe COVID-19 survivors from a Latin American cohort. Materials and methods: A prospective multicenter study from the Latin American Registry of Cardiovascular Disease and COVID-19, analyzed data on 272 severe COVID-19 patients from 7 institutions in 5 countries (Colombia, Dominican Republic, Ecuador, Argentina, and Paraguay). Long-term follow-up assessed demographics characteristics, comorbidities, lifestyle, cardiovascular complications, and oral health. Logistic regression in R software identified factors associated with xerostomia. Results: Xerostomia was reported in 20.6% of patients. Among affected individuals, 53.6% were female, while women represented 35.6% of those without the condition. In the overall cohort, the most common comorbidities were overweight/obesity (57.0%), hypertension (55.9%), and dyslipidemia (32.0%). Patients with xerostomia had higher rates of dyslipidemia (48.2% vs. 27.8%) and asthma/COPD (16.1% vs. 4.2%) compared to the group without xerostomia. In multivariable logistic regression, asthma/COPD (aOR: 5.14; 95% CI: 1.76-15.7), palpitations (aOR: 2.47; 95% CI: 1.04-5.94), and chest pain (aOR: 3.74; 95% CI: 1.67-8.43) were independently associated with xerostomia. Conversely, male sex was associated with lower odds of reporting xerostomia (aOR: 0.47; 95% CI: 0.24-0.89). Conclusion: These findings underscore the need for clinicians to actively assess oral health symptoms such as xerostomia in post-COVID care, particularly in patients with cardiopulmonary comorbidities and persistent systemic symptoms.
