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
Accurate assessment of site of obstruction in Obstructive Sleep Apnoea (OSA) is key to its effective management, especially the surgical intervention. Currently, Drug induced sleep endoscopy (DISE) is widely used to assess the obstruction during sleep as assessing during physiologic sleep is impractical and cumbersome. To assess the site, pattern and degree of airway obstruction in patients with moderate to severe obstructive sleep apnoea using DISE and to find a co-relation of DISE findings with awake fibreoptic assessment and severity of OSA. 41 adult patients (29 males, 12 females, mean AHI 40.58 ± 16.94, mean age 54 ± 9.15 years underwent awake fibreoptic nasal endoscopy in the outpatient department and propofol induced DISE in the main operation theatre. The site/s, degree and pattern of obstruction were recorded as per VOTE and Fujita classification. Velum was the commonest site of collapse followed by oropharynx, base of tongue and epiglottis. All had multilevel collapse with velum, oropharynx and base of tongue being the most common combination. At velum, base of tongue and epiglottis, antero-posterior pattern of collapse was commonest and at oropharynx lateral pattern of collapse was the commonest. We found no difference in the site, pattern or severity of collapse between the moderate and severe group though there was a tendency of epiglottis collapse being present more frequently in severe OSA. Awake fibreoptic endoscopic evaluation was able to assess the collapse at level of velum with higher sensitivity but with poor specificity. There was high chances of missing a hypopharyngeal collapse with fibreoptic endoscopic evaluation.
