Is it important to stabilize palatopharyngeus muscle to pterygomandibular raphe under vision during surgery for OSA?

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
purposeAccess the importance of visualizing the pterygomandibular raphae (PMR) while fixing palatopharyngeous (PPM) muscle to the pterygomandibular raphae (PMR).
methodsRandomized controlled trial. First group, forty-two OSA patients performed either Anterolateral advancement pharyngoplasty (ALA) or Barbed reposition pharyngoplasty (BRP) while visualizing the PMR according to the following criteria: age between 21 and 60 years, body mass index (BMI) < 35, and patients with lateral pharyngeal collapse diagnosed with drug induced sleep endoscopy (DISE). The results were compared to the second control group of 42 patients performed the same procedures without exposing the PMR.
resultsPMR was bilaterally present in 27 (64.28%) patients and bilaterally absent in 5 (11.8%) patients while unilateral in 10 (23.9%) patients. PSG findings in group 1: Apnea hypopnea index (AHI) decreased from 40.84 ± 26.93 to 14.81 ± 7.43 (P < 0.001), mean Lowest oxygen saturation (LOS) significantly increased from 79.25 ± 14.93 to 89.92 ± 10.7 (P < 0.001) and Epworth sleepiness scale (ESS) significantly dropped from 13.25 ± 4.65 to 6.1 ± 2.06 (P < 0.001). Group 2 results showed AHI decrease from 27.50 ± 11.56 to 11.22 ± 7.63 (P ≤ 0.001), LOS increased from 81.86 ± 6.41 to 90.21 ± 3.70 and ESS dropped from 14.95 ± 3.72 to 7.91 ± 3.05. The difference between both groups was not statistically significant (P > 0.001).
conclusionFixation of PPM to the PMR under direct vision doesn't significantly affect the surgical outcomes but can increase the procedure efficiency and reduce complication rate keeping in mind that PMR may be absent in some patients.
