Management of difficult airway among patients with oropharyngeal angioedema.
Article in The Laryngoscope, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
objectiveThe objective of our study was to assess the impact of a multidisciplinary difficult airway response team (DART), a quality improvement program, in the management of patients with difficult airway associated with oropharyngeal angioedema patients.
methodsIndividual retrospective cohort study. Retrospective review of patient charts from July 2003 to June 2008 (pre-DART) and retrospective review of prospectively collected data from July 2008 to June 2013 (post-DART). Patients with angioedema were identified using International Classification of Disease codes 995.1 and 277.6. Patients were included in the study if an otolaryngologist was consulted for airway management. Patients were excluded if they had a history of angioedema but no active issues. Patient characteristics, airway evaluation, and interventions (intubation/surgical airway) were compared between the pre-DART and post-DART cohort.
resultsThe DART team attended to 27 patients with advanced oropharyngeal angioedema. Response time averaged 3.36 minutes. Preintubation fiberoptic airway evaluations were performed in 81% of the post-DART cohort and 56% of the pre-DART cohort. The incidence of patients requiring intubation was higher in the post-DART cohort (18 out of 27 [67%]) than the pre-DART (14 out of 36 [39%]) cohort. One emergency cricothyroidotomy was performed in each of the post-DART and pre-DART cohorts.
conclusionAngioedema of the larynx is a predictor of intubation or cricothyroidotomy. Fiberoptic-guided intubation is primarily used for establishing airway in angioedema patients. A multidisciplinary standardized approach such as the DART program offers adequate time and resources for airway evaluation prior to intervention and allows fewer number of attempts to secure an airway.
