1 · What the graph read from 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.

2 · The registry

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

Introduction: Traumatic patients with cervical spine motion restriction have difficulty with endotracheal intubation (ETI) due to the limitations of neck movement and mouth opening. Nevertheless, the removal of the cervical collar for ETI in a prehospital setting may lead to a deterioration in neurological outcomes. This study compares the success rate of ETI utilizing a video laryngoscope (VL) on a manikin, contrasting manual in-line stabilization (MILS) without a cervical hard collar against full immobilization. Methods: A randomized, non-crossover study was conducted involving 56 paramedic students assigned by SNOSE to utilize various box sizes for VL intubation with MILS without a cervical hard collar or full immobilization technique on a manikin. The primary outcome was the intubation success rate. Secondary outcomes included attempts, time for successful intubation, and Cormack-Lehane classification. Results: Fifty-six participants were evaluated; 28 were in the full immobilization group, and another 28 were in the MILS without cervical hard collar group. Baseline characteristics showed no difference between both groups. The success rate of VL intubation showed no difference between the full immobilization group and the MILS without a cervical hard collar group (28 [100%] vs 28 [100%]; 24 [85.71%] vs 27 [96.43%] on first attempt; 4 [14.29%] vs 1 [3.57%] on second attempt; p-value 0.352). Time required to perform successful intubation (median [IQR] 17.20 [12.53, 24.40] vs 17.53 [14.06, 23.73], p-value 0.694) and Cormack-Lehane classification (11 [39.29%] vs 10 [35.71%] in grade I; 16 [57.14%] vs 17 [60.71%] in grade II; 1 [3.57%] vs 1 [3.57%] in grade III, p-value 1.000) showed no statistical difference between the two groups. Conclusion: It is unnecessary to remove the cervical hard collar when performing endotracheal intubation while using a video laryngoscope.
