Laryngeal and Voice Disorders in Patients with Pulmonary Tuberculosis.

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
introductionLaryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx. The aim of the present work was to study the laryngostroboscopic features and voice quality of patients with laryngeal TB secondary to pulmonary TB. MATERIALS AND
methodsParticipants were 35 patients diagnosed as having pulmonary TB and dysphonia. All patients had a complete history, clinical and laboratory workup. Patients were assessed using a protocol of voice assessment which included Auditory-perceptual analysis of voice, voice analysis using the Multidimensional Voice Profile (MDVP), and laryngostroboscopy.
resultsThe participants were 24 males and 11 females and their mean age was 43.7 years. The voice acoustic analysis revealed a significant difference from normal in jitter percent, shimmer percent, and harmonic to noise (H/N) ratio. Laryngeal gross lesions were found in 11 patients while the other 24 patients had normal laryngoscopic findings with nonspecific stroboscopic changes as reduced mucosal waves and mild glottic gap. Diffuse lesion of the whole vocal folds was found in 5 patients and anterior predilection in 4 patients. The type of lesions were granulomatous lesions in 7 patients and non-specific inflammatory mild exophytic lesions in 4 patients.
conclusionsVoice disorders in pulmonary TB include disturbance in the mechanism of voice production with or without detectable laryngeal lesion. Videostroboscopy has the advantage of showing the extension of laryngeal involvement, vocal folds vibrations, and mucosal waves.
