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 and Aim: This study evaluates the effectiveness of long-acting antihypertensive drugs (clonidine and enalaprilat) in blunting the intubation response. Also, the study seeks to determine how effectively clonidine and enalaprilat can maintain stable haemodynamics during a change in position. Methods: After ethical committee approval and trial registration, a double-blinded, randomised controlled trial was conducted with 71 consenting patients scheduled for elective spine surgery in a prone position under general anaesthesia. Group C received clonidine 2 μg/kg, and Group E received enalaprilat 1.25 mg diluted in normal saline as an intravenous infusion given over 10 min before induction of anaesthesia. The changes in heart rate (HR) and blood pressure (BP) in response to the infusion of the study drugs, induction, tracheal intubation and change in position were recorded. Results: Clonidine infusion caused a significant fall in heart rate post-infusion and post-induction with propofol (p value <0.05). Both clonidine and enalaprilat caused a significant fall in mean arterial pressure (MAP) post-infusion and post-induction (p value <0.05). Clonidine effectively blunted the intubation response with no increase in HR and MAP following intubation. Enalaprilat caused a significant rise in HR in response to intubation. On proning, there was a significant fall in MAP in both groups. Conclusion: Clonidine is effective in blunting the intubation response. Preoperative infusion of clonidine and enalaprilat causes hypotension during a change of position.
