1 · What the graph read from it

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.

2 · The registry

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

backgroundPatients undergoing metabolic bariatric surgery (MBS) have a high prevalence of obstructive sleep apnea (OSA), increasing the risk of postoperative respiratory complications. While tongue thickness has been linked to OSA severity, its role as a predictor of postoperative hypoxemia and other complications remains unclear. This study is the first to evaluate whether preoperative ultrasound-measured tongue thickness correlates with postoperative respiratory outcomes and complications in patients undergoing MBS. 

methodsThis prospective observational cohort study included 119 adult patients undergoing robotic-assisted laparoscopic MBS. Preoperative point-of-care ultrasound was used to measure sagittal and coronal tongue thickness. Continuous postoperative monitoring was performed using the Masimo RAD-97™ system for up to 14 h. Outcomes included desaturation events, respiratory and pulse events, and 30-day postoperative complications. Correlations between tongue thickness and clinical outcomes were analyzed and stratified by OSA status.

resultsLarger tongue dimensions were modestly associated with postoperative desaturation events. Significant time-dependent correlations were observed during the 0-6-h postoperative period (ρ = 0.15-0.34). Patients with OSA showed correlations with desaturations during the first 2 h, while patients without OSA had associations during the 4-6-h window. There were no significant differences in tongue size for those with common 30-day complications (p > 0.05).

conclusionsUltrasound-measured tongue thickness is associated with early postoperative oxygen desaturation in patients undergoing MBS, independent of OSA diagnosis. These findings suggest that tongue ultrasound may serve as a noninvasive tool for preoperative respiratory risk stratification. Further studies into comprehensive preoperative anatomical measurements to enhance risk stratification are warranted.
