Oral Mucosal Human Papillomavirus and Epstein-Bar Virus Rates in Patients with Dry Mouth and/or Sjögren's Syndrome in a Hungarian Cohort.
Article in Oral health & preventive dentistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo find an association between oral mucosal human papilloma- and/or Epstein-Barr (HPV, EBV) virus infection in patients with dry mouth and/or Sjögren's syndrome (SS) compared to healthy controls and to find connections with salivary gland histopathological alterations. MATERIALS AND
methodsNinety-two participants were divided into four groups: 1. healthy controls (n = 32); 2. xerostomia (n = 28); 3. hyposalivation (n = 22); and 4. SS groups (n = 10). To detect virus infection brush biopsy was outlined in all groups. Detections of virus-specific sequences were achieved with polymerase chain reaction (PCR). Lip biopsy and histopathological assessment was performed in groups 2, 3 and 4.
resultsHPV positivity of oral mucosal cells was shown in group 1: 1 (3.12%); group 2: 3 (10.7%); group 3: 2 (8.26%); and in group 4: 0 of the samples. EBV was present in group 1: 14 (43.7%); group 2: 17 (60.7%); group 3: 6 (27.3%); and in group 4: 5 (50%) of the cases. There was no statistically significant difference between the attributes. Intact salivary gland in 28.2%, chronic sialadenitis in 28.2%, stromal fibrosis in 6.5%, lipomatous atrophy in 8.6%, fibrous atrophy in 6.5% and positive focus score (SS) in 26.1% were found in the subjects. Neither HPV nor EBV infection caused statistically significantly more histological abnormalities.
conclusionOrofacial mucosal HPV and/or EBV DNA rates did not differ statistically significantly in patients with xerostomia or hyposalivation or SS compared to healthy controls, therefore, it cannot prove the provocative role of these viruses in dry mouth and/or SS. Neither dry mouth nor SS were accompanied by statistically significantly more salivary gland alterations in HPV- and/or EBV-positive subjects; these alterations are frequent in the virus-negative cases too.
