Reversibility of Pulmonary Hypertension and RV Dysfunction After Adenotonsillectomy in Children and Adolescents From Ethiopia.
Article in Sage open pediatrics. 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
Aim: To determine the prevalence of pulmonary hypertension (PH), identify associated factors, and evaluate outcomes after adenotonsillectomy in children and adolescents with adeno-tonsillar hypertrophy (ATH) in a low-resource setting. Methods: We retrospectively analyzed 1500 patients ≤ 20 years undergoing adenotonsillectomy for ATH in Hawassa, Ethiopia (2022-2025). Pulmonary pressure was estimated via tricuspid regurgitation or pulmonary acceleration time; right ventricular function was assessed with TAPSE and RVMPI. Logistic regression identified PH predictors, and the Friedman test compared pre- and 12-week postoperative measurements. Results: PH prevalence was 5.9%. Independent predictors included wasting, overweight/obesity, AN ratio > 0.75, daytime mouth breathing, stertor, and obstructive sleep apnea. Among 89 affected patients, 8 had longitudinal and 6 global RV dysfunction. PH and RV dysfunction resolved by 12 weeks post-surgery ( Conclusion: PH affects a subset of children with ATH but is showed significant improvement following adenotonsillectomy, emphasizing early detection and surgical intervention.
