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

Background: Laryngoscopy and endotracheal intubation evoke significant hemodynamic responses, particularly in patients undergoing coronary artery bypass grafting (CABG) who have compromised cardiac reserves. This study aimed to compare the hemodynamic effects of the C-MAC video laryngoscope (VL) with those of the conventional Macintosh laryngoscope (MC) in patients undergoing elective CABG. Methods: This randomized controlled trial included 86 patients scheduled for elective CABG, who were randomly assigned to intubation with either the MC group or the C-MAC VL group. Hemodynamic parameters, including heart rate, systolic, diastolic, and mean arterial pressures, were recorded at five time points (prelaryngoscopy baseline to 10 min postintubation). Secondary outcomes included the intubation success rate, duration of laryngoscopy and intubation, glottic visualization, and complications. Results: Two-way repeated measures ANOVA revealed no significant group effect or group-by-time interaction for any hemodynamic variable (all Conclusion: In patients undergoing CABG, C-MAC VL and conventional MC result in similar hemodynamic responses. The choice of laryngoscope may be guided by airway considerations and operator experience rather than anticipated cardiovascular effects.
