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
purposeTo minimize post-intubation laryngeal injury it is important to identify the factors that contribute to the development of these lesions. Previous literature has been inconsistent. This survey aims to investigate experts' opinions on the various factors associated with severe laryngeal injury following intubation in the pediatric population and to determine whether these opinions influence the treatment of patients with one or more of these factors.
methodsA multiple-choice questionnaire with the possibility to provide open text answers was developed and sent by email, WhatsApp and Siilo to members of the scientific societies of anesthesiology, pediatric intensive care, emergency medicine and ear nose throat surgeons worldwide. Responses were analyzed thematically.
resultsA total of 363 physicians worldwide responded to the survey, mainly anesthesiologists (31%), intensivists (35%) and ENT surgeons (29%). The majority of the respondents (69%) had over 10 years of experience in pediatric airway management. Overall, factors with the highest agreement (> 80% of respondents) were 'traumatic intubation', 'multiple intubation attempts', 'the use of oversized tubes', 'skill level of the intubator', 'repeated intubations' and 'period of intubation', specifically in small (weight < 2 kg, age < 1 year) children. The factors 'use of muscle relaxants' and 'biological sex' were not considered relevant. In accordance with their daily practice, physicians from different specialties reported varying factors as being relevant. These assumptions influence their routine decisions regarding intubation and extubation procedures.
conclusionsAlthough not extensively supported by literature, the majority of the experts indicate that factors such as 'traumatic intubation', 'multiple intubation attempts', 'oversized tubes', 'skill level of the intubator', 'repeated intubations' and 'period of intubation' are the most relevant factors in the development of post-intubation severe laryngeal injury in the pediatric population. Physicians from different specialisms also highlight specialism specific factors they consider most significant which influence their day-to-day clinical practice.
