1 · What the graph read from 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.

2 · The registry

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

objectivesAlthough superficial fungal infections of the oral and maxillofacial region are common, deep fungal infections remain unfamiliar. We investigated the prevalence of fungal infections in this location in Thailand from specimens examined in the Department of Oral and Maxillofacial Pathology over a 50-year period. MATERIALS AND

methodsCases diagnosed as fungal infections in our archive were selected. Demographic data, risk factors, clinical and radiographic features, clinical differential diagnoses and treatments were analyzed.

resultsOf 22,070 biopsied specimens, 41 cases (0.19%) were fungal infections in this location. The prevalence increased in the last decade. Approximately 71% were candidiasis, while 29% constituted deep infections including mucormycosis, aspergillosis and histoplasmosis. Fungal infections predominantly affected elderly individuals (mean age: 62.1 years). Both superficial and deep types exhibited a female predominance with a ratio of 1:3.8 and 1:3, respectively. About 60% of patients were associated with risk factors, namely, betel quid chewing, diabetes mellitus and human immunodeficiency virus infection. Clinically misdiagnosed chronic hyperplastic candidiasis as erythroleukoplakia/lichen planus, and deep fungal infections as osteomyelitis/oral squamous cell carcinoma were frequently observed. All candidiasis were treated with topical antifungal drugs, while mucormycosis and histoplasmosis required systemic antifungal therapy.

conclusionsFungal infections constituted less than 1% among biopsied specimens. The majority of fungal infections were clinically misdiagnosed. Currently, histopathologic examinations using proper special stains play a vital role to achieve a definite diagnosis. CLINICAL RELEVANCE: Unfamiliarity with deep fungal infections in the oral and maxillofacial region among oral healthcare personnel may lead to misdiagnosis and inappropriate treatment. Awareness of fungal infections in this area must be encouraged.
