Comparative evaluation of King Vision videolaryngoscope channeled and non-channeled blades with direct laryngoscope for intubation performance and skill retention by medical students: a randomized cross over two period study.

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
purposeA videolaryngoscope(VL) with an intubation conduit like KingVision channeled(KVC) blade may provide an added advantage over a non-channeled VL like a KingVision non-channeled (KVNC) blade and direct laryngoscope (DL) for acquiring and retention of intubation skills, especially in novices.
methodsIn this prospective two-period randomized crossover trial, one hundred medical students used three laryngoscopes KVC, KVNC and DL for intubation following standardized training with the study devices using a Laerdal Airway Management Trainer. After one month, all participants attempted intubation, in the same manner, using all devices. The duration of intubation, modified Cormack-Lehane (CL) grade, percentage of glottic opening (POGO) score, first-attempt success, number of attempts, ease of intubation and dental trauma was recorded. The retention of intubation skills after 1 month was also assessed on the same parameters.
resultsMedian intubation times of KVC and DL were comparable and significantly better than KVNC (P < 0.001). The median POGO score was better with both videolaryngoscopes when compared with DL. The ease of intubation (P < 0.0012) and first-attempt success rate (P = 0.001) at the time '0' was significantly better with KVC compared to KVNC and DL. KVC fared better with respect to these intubation parameters during intubation after one month as well.
conclusionKVC performed better in terms of time to intubation, success rate and ease of procedure as compared to KVNC and DL, both for acquisition and retention of skill. Hence, we advocate that KVC should be the preferred device over KVNC and DL for teaching intubation skills to novices.
