A Novel Grading System for Salpingopharyngeal Fold Hypertrophy in Obstructive Sleep Apnoea.
Article in Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The present study aimed at reporting the incidence of Salpingopharyngeal Fold (SPF) hypertrophy on Drug Induced Sleep Endoscopy (DISE) in patients with Obstructive Sleep Apnoea (OSA, validate a grading system and analyse the impact of various grades on the clinical presentation while ascertaining its relation with Apnoea-Hypopnoea Index (AHI). A retrospective analysis of 169 patients with polysomnographic confirmation of obstructive sleep apnoea has been done in the study. The DISE video data of 169 patients was evaluated by two ENT surgeons individually and they graded the hypertrophy of the fold as Grade 0 being normal anatomy, Grade 1 being hypertrophy causing partial obstruction and Grade 2 being hypertrophy causing complete obstruction of lateral pharyngeal wall. It was found that the presence of SPF hypertrophy independently adds considerably to the severity of the obstruction, attributing to lateral collapse at the upper retropalatal level and also significantly increases AHI. It is thus advised to consider the grade of SPF hypertrophy while surgically planning the management of patients with OSA.
