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
Background and Objectives: Congenital choanal atresia is a rare condition that occurs in approximately 1 in 7,000 to 8,000 live births and involves the obstruction of the posterior nasal airway. It may present as either unilateral or bilateral, with bilateral cases being more severe due to the risk of immediate neonatal respiratory distress. Bilateral congenital choanal atresia (BCCA) necessitates prompt medical intervention to prevent cyanosis and significant breathing difficulties. This study focuses on the timing of surgery, the duration of stent use, and postoperative care in patients with bilateral congenital choanal atresia who underwent endoscopic transnasal surgery. Unlike previous studies, this research emphasizes the efficacy of an extended stenting period and introduces novel stenting techniques aimed at reducing restenosis. Methods: From 2018 to 2021, three patients with BCCA underwent transnasal surgery that included the placement of stents. We retrospectively analyzed their medical records, focusing on the surgical outcomes in relation to the duration of stent placement and postoperative care. A novel approach was adopted, involving the use of customized stent sizes tailored to the specific anatomical factors of each patient, which facilitated improved neochoana maintenance. Results: The average interval from diagnosis to surgery was 3.6 weeks. Surgery was successful in all cases, and the stent was removed after 6 months. In all patients, stable neochoanae were maintained without significant restenosis. Additionally, we observed that maintaining a stent for a period longer than previously recommended significantly reduced the risk of restenosis compared to the shorter durations used in earlier studies. Conclusion: Our study suggests that an extended stenting period of 6 months or more is crucial for maintaining long-term patency in patients with BCCA. This approach could lead to a more reliable stenting protocol and improved postoperative care, potentially establishing a new standard for managing BCCA.
