Hemodynamic effects of topical lidocaine on the laryngoscope blade and trachea during endotracheal intubation: a prospective, double-blind, randomized study.
Trial report in Journal of anesthesia, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
purposeMinimizing hemodynamic changes during the peri-intubation period is a concern for anesthesiologists. We investigated the effect of lidocaine sprayed on the laryngoscope blade and trachea on hemodynamics during direct laryngoscopic intubation.
methodsSeventy-two patients were randomly allocated to one of four groups: 10% lidocaine was sprayed either on the laryngoscope blade (group L), on the trachea (group V), or on the laryngoscope blade and the trachea (group LV). No lidocaine was used in group C. Anesthesia was induced in all patients with remifentanil (effect site concentration: 4.0 ng/ml) and propofol (effect site concentration 4.0 μg/ml) continuous infusion using a target control infusion (TCI) device. Mean arterial pressure (MAP) and heart rate (HR) were recorded during the peri-intubation period.
resultsChanges in MAP and HR over time were markedly different among the four groups (P < 0.05). MAP at 1 min post-intubation was significantly lower in groups L, V, and LV than in group C (86.1 ± 12.7, 85.3 ± 12.6, and 83.7 ± 13.1 vs. 106.3 ± 22.9 mmHg, P < 0.01). Maximum MAP values were lower in groups L and LV than in group C (P < 0.05). HRs at 1, 2, and 3 min post-intubation were lower in group LV than in group C (70.4 ± 9.0 vs. 84.2 ± 15.3; 64.0 ± 8.1 vs. 79.2 ± 15.4; 61.6 ± 8.3 vs. 77.2 ± 14.5 beats/min, P < 0.01, respectively).
conclusionsLidocaine sprayed on the laryngoscope blade and/or trachea reduced the hemodynamic response to laryngoscopic intubation during the post-intubation period following anesthetic induction with remifentanil and propofol using a TCI device.
