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
objectiveExpansion sphincter pharyngoplasty (ESP) is an effective surgical technique for treating obstructive sleep apnea syndrome (OSAS). This study evaluates the impact of ESP on cardiac complications and morbidities by analyzing patients’ echocardiographic findings.
methods25 OSAS patients (aged 18–65) intolerant to Continuous Positive Airway Pressure (CPAP) therapy, who underwent ESP surgery between May 2019 and August 2022. Preoperative and postoperative (six months after surgery) polysomnography (PSG) data and echocardiographic findings were evaluated. Surgical success based on Sher criteria was defined by a > 50% reduction in the apnea-hypopnea index (AHI) and postoperative AHI < 20. The Epworth Sleepiness Scale was used to assess symptomatic improvement.
resultsThe mean AHI decreased from 27.76 ± 18.54 preoperatively to 18.08 ± 18.82 postoperatively (p < 0.001), with a surgical success rate of 56%. No significant correlation was found between success rate or AHI change and gender, age, or disease severity. In the successful group, significant improvements were seen in right ventricular parameters, including systolic pulmonary artery pressure (SPAP) (28.00 ± 4.00 to 24.79 ± 2.54, p = 0.006), pulmonary vascular resistance (PVR) (1.79 ± 0.33 to 1.61 ± 0.27, p = 0.013), and right ventricular thickness (RV) (0.53 ± 0.10 to 0.46 ± 0.06, p = 0.008). Tricuspid annular plane systolic excursion (TAPSE) also increased significantly (2.22 ± 0.15 to 2.37 ± 0.15, p = 0.01).
conclusionIn our study involving OSAS patients without known cardiac disease, follow-up after successful ESP surgery demonstrated significant improvement in echocardiographic parameters, particularly those associated with right ventricular function. Appropriate patient selection combined with effective ESP surgery can lead to substantial reductions in AHI values, potentially contributing to the prevention of subclinical cardiac complications in this patient population.
