Predictive factors for surgical outcomes and symptom persistence after uvulopalatopharyngoplasty in patients with obstructive sleep apnea.
Article in Head & face medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveFor individuals diagnosed with obstructive sleep apnea (OSA), uvulopalatopharyngoplasty (UPPP) represents a frequently utilized surgical intervention, yet its postoperative efficacy varies significantly among individuals. Identifying key preoperative predictors of surgical success is crucial for optimizing patient selection and enabling personalized treatment strategies.
methodsThis retrospective study included 191 OSA patients who underwent UPPP. Postoperative outcomes were assessed at a three-month follow-up, and a multivariate logistic regression model combining body mass index (BMI), apnea–hypopnea index (AHI), peripheral blood oxygen saturation (SpO₂), Epworth Sleepiness Scale (ESS) score, visual analogue scale (VAS) score, and Friedman staging was constructed to predict surgical efficacy. Surgical success was defined as a postoperative AHI reduction > 50% or a final AHI < 20 events/hour. Multivariate logistic regression and ROC curve analysis were used to identify predictors of surgical efficacy.
resultsUPPP significantly reduced AHI, ESS, and VAS scores, while elevating SpO₂, with 64.4% of patients meeting efficacy criteria. Preoperative SpO₂ (OR = 1.297), ESS (OR = 1.351), and VAS (OR = 3.635) were independent positive predictors, while BMI (OR = 0.644) was a negative predictor. Friedman stage I (OR = 0.054) and II (OR = 0.002) predicted better outcomes than stage III. The combined prediction model achieved an area under the curve (AUC) of 0.972. Patients with fewer residual symptoms postoperatively had higher preoperative SpO₂, lower BMI and VAS scores, and significantly higher satisfaction (95.8% vs. 62.2%). Complication rates were lower in both the surgical success group and the low-residual symptom groups.
conclusionThe multivariate model integrating key preoperative predictors demonstrated excellent discriminative performance (AUC = 0.972) and offers substantial clinical utility for improving preoperative risk assessment, optimizing surgical decision-making, and enhancing postoperative patient satisfaction.
