Observational studyTherapeutic advances in respiratory disease
Subglottic cysts as an uncommon cause of upper airway obstruction: a 12-year retrospective study.
Observational study in Therapeutic advances in respiratory disease. 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
backgroundSubglottic cysts (SGCs) are a rare disease with a high misdiagnosis rate.
objectivesWe aim to improve the diagnostic and management ability of pediatricians for SGCs by analyzing the clinical characteristics of confirmed cases.
designObservational, retrospective cohort studyMethods:We enrolled children diagnosed with SGCs admitted to the Children's Hospital of Chongqing Medical University between January 2010 and December 2022. Clinical characteristics data were collected and analyzed retrospectively. Patients were regularly followed up for 1 year post-treatment or discharge.
resultsEleven children were included in this retrospective study. There were nine (9/11, 81.8%) males and two (2/11, 18.2%) females, and the median age was 15 months. Eight (72.7%) were premature. Seven (63.6%) patients had a history of intubation. The common manifestations were stridor (72.7%), wet cough (72.7%), shortness of breath (72.7%), and dyspnea (54.5%). The average diagnosis time was 7 months. The most common comorbidity was laryngopharyngeal reflux disease (LPRD, 45.5%), followed by laryngomalacia (27.3%), bronchopulmonary dysplasia (27.3%), bronchial stenosis (18.2%), and adenoid hypertrophy ( 18.2%). The obstruction degree of SGCs was "3" (51%-75% occlusion) or higher in eight (72.7%) patients. Two (18.2%) patients experienced recurrence after initial cyst aspiration and subsequently underwent successful laryngoscopy marsupialization. Ultimately, eight (72.7%) patients achieved complete recovery after endoscopic marsupialization.
conclusionSGCs should be considered in the differential diagnosis of children, especially those with a history of prematurity and/or perinatal intubation, who present with stridor, wet cough, and respiratory distress. Endoscopic evaluation is crucial for both definitive diagnosis and guiding effective treatment.
