Comparison of different types of stylets with no-stylet technique for intubation with C-MAC D-Blade® videolaryngoscope in simulated difficult airway: A prospective randomized study.
Article in Turkish journal of anaesthesiology and reanimation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe angulated C-MAC D-Blade videolaryngoscope (VL) is designed for difficult intubation and may not be compatible with standard PVC endotracheal tubes.
objectivePresent study was planned to compare efficacy of C-MAC, D-blade VL using endotracheal tube with three different stylets versus No stylet in patients undergoing tracheal intubation with simulated difficult airway.
methodsAfter obtaining written consent and IEC approval, total 144 adult patients were allocated to four groups of 36 each using no stylet or different types of stylets. The four groups were Group NS: No stylet; Group CS: C-MAC stylet; Group DS: D-blade type stylet; Group HS: hockey-stick shaped stylet. A rigid appropriate sized Philadelphia cervical collar was placed around the neck to simulate difficult airway and C-MAC D-Blade VL was used for intubation. The duration of each intubation stage and attempts were evaluated. Statistical analysis was performed using SPSS 22.0 for Windows and appropriate tests for different variables were applied. Appropriately, Student's t test, Chi-square test, Mann-Whitney U test and one-way ANOVA test were applied.
resultsSimilar Cormack Lehane grade glottic view was observed in all groups. The number of attempts and duration of intubation was significantly greater using NS than for other groups. Additional laryngeal manipulation, was required in all cases in Group NS, compared to one, zero and two cases in group CS, DS and HS respectively (p<0.001).
conclusionUse of Hockey stick shaped, D blade shaped stylet and C Mac stylet decreased the total intubation duration in patients with simulated difficult airway.
