Immediate impact of pharyngeal surgery on respiratory parameters in adults with obstructive sleep apnea.

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
purposeOne of the concerns regarding surgical treatment of the obstructive sleep apnea syndrome (OSAS) has been the possibility that these patients may experience a higher rate of perioperative complications, which could be aggravated by the upper airway edema caused by surgical trauma. The purpose of this study was to evaluate the immediate impact of pharyngeal surgery on the respiratory parameters of adult patients with OSAS.
methodsTwenty-three adults with moderate to severe OSAS and indications for pharyngeal surgery (with or without nasal surgery) were consecutively selected. The subjects underwent surgical treatment and monitoring of sleep parameters preoperatively (by type I polysomnography, PSG) and in the immediate postoperative period (arterial tonometry).
resultsTwenty-two subjects, aged 20 to 59 years (mean ± SD, 38.0 ± 12.1 years), were included in the study. Nineteen (86.4%) were male. The mean apnea-hypopnea index (AHI) was 59.3 ± 26.0 events/h. Comparison between preoperative PSG and postoperative arterial tonometry revealed statistically significant reductions in AHI (p = 0.03), respiratory disturbance index (RDI) (p = 0.05), and oxygen desaturation index (p = 0.001), as well as increases in nadir oxyhemoglobin saturation (p = 0.003) and percentage of REM sleep (p = 0.01).
conclusionsIn this sample of patients with moderate and severe OSAS who underwent pharyngeal surgery, the vast majority of patients did not exhibit any deterioration of respiratory parameters in the immediate postoperative period. Conversely, there was a significant improvement in the parameters.
