Right Ventricular Function and Pulmonary Arterial Coupling in Paediatric 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
purposeRight ventricular (RV) dysfunction and increased pulmonary arterial (PA) pressure may occur in children with obstructive sleep apnea (OSA). Long-term data on RV-PA coupling in children with OSA with or without adenotonsillectomy are absent.
methodsThis prospective cohort study included children aged 5 to 12 years diagnosed with tonsillar hypertrophy and moderate-to-severe OSA. All subjects underwent echocardiographic assessment and sleep study at least 5 years since initial recruitment. Right atrial, RV function and indexed pulmonary artery acceleration time (PAATi) were evaluated. RV-PA coupling was assessed by tricuspid annular plane systolic excursion (TAPSE) / PAATi and RV global longitudinal strain (GLS) / PAATi.
resultsWe evaluated 160 subjects, including 38 with OSA who declined adenotonsillectomy (Group I), 80 with OSA post-adenotonsillectomy (Group II), and 42 controls (Group III). Baseline demographics were similar across groups. At a mean follow-up of 7.2 ± 2.5 years, the latest OAHI did not differ significantly between the two OSA groups. Echocardiographic assessment revealed small intergroup differences in RA total strain, peak tricuspid annular systolic velocity, RVGLS and PAATi, whereas TAPSE, RV fractional area change and systolic strain rate were comparable across groups. Importantly, RV-PA coupling indices did not differ significantly among the three groups. Furthermore, within the OSA cohort, neither follow-up duration nor current OAHI severity correlated significantly with RV function or RV-PA coupling indices.
conclusionsRV function and RV-PA coupling are preserved in adolescents and young adults with a childhood diagnosis of OSA, irrespective of prior adenotonsillectomy.
