Comparison of left ventricular diastolic function parameters in patients induced with propofol and etomidate: A randomized clinical trial.

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: Anesthetic agents like propofol and etomidate are known to affect intracellular calcium homeostasis during diastole. Hence, this study has been designed to study the effects of etomidate and propofol on left ventricular diastolic function in adults (>18 years) undergoing elective noncardiac surgery under general anaesthesia. Material and Methods: E-wave velocity, septal and lateral e' velocities, left atrial volume index (LAVI), and tricuspid regurgitation maximum jet velocity (TRVmax) were measured before and after induction of anesthesia (etomidate and propofol). Results: A total of 187 patients were screened, and parameters from 157 patients were analyzed in this study. There was a statistically significant decrease in the mean E velocity, septal e', and lateral e' velocities with both propofol and etomidate. The difference-in-difference analysis revealed that etomidate caused a statistically significant reduction in E velocity (-11.59 ± 6.61 vs. -6.46 ± 9.84, Conclusions: This study found that anaesthesia induction with propofol and etomidate in adults resulted in a statistically significant decrease in E-wave, septal, and lateral e' velocities within the groups. The reduction in E-wave velocity caused by etomidate was more profound when compared with propofol. While both propofol and etomidate may mildly worsen certain parameters of diastolic function, this study did not demonstrate any worsening of diastolic parameters like LAVI, TRVmax, and E/e'.
