A randomized controlled study on the visual grading of the glottis and the hemodynamics response to laryngoscopy when using I-View and MacGrath Mac videolaryngoscopes in super obese patients.
Trial report in Journal of clinical monitoring and computing, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundVideolaryngoscopes improve visualization of glottic in morbidly obese patients. Super-obesity is one of the risk factors influencing probability of difficult mask ventilation and difficult intubation. Super-obese (BMI > 50 kg/m
methodsIn prospective observational study we decided to compare glottis view during intubation using I-view and McGrath Mac videolaryngoscopes in super obese patients. Patients were randomly allocated into group M (McGrath Mac) or group I (I-View). Obtained view was analyzed regarding POGO (Percentage Of Glottis Opening) scale and the necessity to use of additional aid like intubation stylet was recorded. Hemodynamic response to videolaryngoscopy was assessed.
resultsAs results POGO score was better in group M when compared to group I: 81.66 ± 22.8% vs 96.66 ± 7.24% (p = 0.0132) in I and V groups respectively. The use of intubation stylet was similar in both groups. The hemodynamic response to videolaryngoscopy was similar between groups.
conclusionThe POGO score was better for McGrath Mac than for I-view videolaryngoscope, however, both devices allowed for safe and effective intubation in super-obese patients. The hemodynamic response to videolaryngoscopy was similar between devices.
