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: "Difficult airway" is the clinical situation in which a conventionally trained anesthesiologist experiences difficulty with mask ventilation, laryngoscopy, and difficulty with tracheal intubation, or both. Associated factors and predictive value difficult airways, maxillofacial surgery study setup is under studied. Objective: To determine the magnitude and associated factors of difficult airways and predictive value of airway examinations among adult patients who underwent maxillofacial surgery at public hospitals in Southern Ethiopia 2022. Methods and materials: An institutional-based multicenter cross-sectional study was conducted among 250 maxillofacial patients from March to 30 June 2022 at selected hospitals. The data were entered into Epi_Data software version 4.3 and analyzed by STATA software version 14. All variables that were statistically significant in bivariate analysis, at the Results: In the current study, the magnitude of difficult airways was 21.2% (95% CI = 16.3-26.1%) and the magnitude of difficult intubation, difficult laryngoscopy, and difficult mask ventilation was 6.4% (95% CI 3.3-9.4%), 9.6% (95% CI 6.1-13%), and 13.6% (95% CI (9.1-16.8%), respectively. History of head and neck surgery adjusted odds ratio (AOR)=6.3, 95% CI (2.85-14.34), cervical collar AOR=4.9, 95% CI (1.96-12.49), and cervical spine injury AOR=2.4, 95% CI (1.07-5.38) were independently and significantly associated with difficulty of airway. Modified Mallampati class and sternomental distance were identified as good preoperative tests to predict difficult laryngoscopy, intubation, and mask ventilation. Conclusion and recommendation: The magnitude of difficult airways was maxillofacial surgery. Among various airway assessment tests, no single test was perfectly accurate. Anaesthesia professionals are recommended to use a combination of preoperative airway assessments.
