Intubation characteristics using modified USB videolaryngoscope: A prospective, randomised study.
Article in Indian journal of anaesthesia, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aims: Videolaryngoscopes with varying characteristics with regard to angulation of blades and video configurations are now available. However, the contribution of each of these in improving ease of intubation is quite different. We evaluated the role of video camera in the performance of laryngoscopy by using the universal serial bus (USB) videolaryngoscope in patients with predicted difficult airway. Methods: Sixty patients in the age group of 25 to 65 years having Mallampati grade III or IV were randomly allocated to two groups. All patients were American Society of Anesthesiologists physical status grade I or II and planned for elective surgical procedure under general anesthesia. USB videolaryngoscope or Macintosh laryngoscope was used for intubation as per group allotted. Comparison of time of endotracheal intubation was our primary outcome measure and it was calculated from the time the laryngoscope tip passes the incisors to the initial appearance of capnography wave. Rate of successful intubation, number of attempts needed for successful tube placement, optimisation manoeuvres used, changes in haemodynamic parameters and airway injuries were evaluated as secondary outcomes. Results: Time for intubation was shorter in the Macintosh group than the USB group ( Conclusion: USB videolaryngoscope reduces the number of attempts required for successful endotracheal intubation compared to Macintosh laryngoscope though it increases the time for intubation in patients with predicted difficult airway.
