Diagnosis of laryngeal tuberculosis in a high TB burden area.

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
purposeThe larynx is the second most commonly affected site in the head and neck region in patients with extrapulmonary tuberculosis (TB). Despite this, the prevalence of laryngeal TB is largely unknown, particularly in areas with a high TB burden. The laboratory diagnosis of TB includes microscopy, culture and molecular testing. The aims of this study were to determine the prevalence of laryngeal TB in patients presenting with laryngeal pathology in a region with a high TB burden and to determine the optimal diagnostic methods for the diagnosis of laryngeal TB.
methodsThis was a prospective descriptive study of 80 adult patients undergoing direct laryngoscopy and biopsy for laryngeal pathology in the Department of Otorhinolaryngology, Universitas Academic Hospital, Bloemfontein, South Africa over a 1 year period. Histopathological and microbiological investigations (microscopy, Xpert MTB/RIF, and TB culture) were performed on all laryngeal biopsies.
resultsFive (6.25%) out of 80 patients were diagnosed with laryngeal TB. In one patient, the Xpert MTB/RIF assay was positive on the laryngeal tissue and histology showed granulomas. Two patients had granulomas on histology although the microbiological tests on the tissue were negative. Two patients had only positive tissue cultures for Mycobacterium tuberculosis. None of the biopsies had positive Ziehl-Neelsen stains.
conclusionThe results suggest that the diagnosis of laryngeal TB required a combination of histopathology, culture and PCR and that the Xpert MTB/RIF assay is not a sensitive test for the diagnosis of laryngeal TB.
