The Prophylaxis Effect of Ephedrine on Hemodynamic Variation in Patients Undergoing Percutaneous Nephrolithotomy Surgery with Spinal Anesthesia.
Trial report in International journal of clinical practice, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Performing spinal anesthesia with at least hemodynamic variation and complications is always challenging for anesthesiologists. In this study, we investigated the effect of ephedrine and placebo on hemodynamic changes in patients undergoing percutaneous nephrolithotomy with spinal anesthesia. Methods: This randomized, double-blind prospective clinical trial was conducted on 120 patients aged 20‒60 years with ASA (American Society of Anesthesiologists) classes I and II. Patients who were candidates for percutaneous nephrolithotomy with spinal anesthesia were divided into intervention (received 1 cc = 5 mg ephedrine) and control groups (received 1 cc normal saline). All vital parameters, including HR (heart rate) and NIBP (noninvasive blood pressure), were recorded perioperatively T0-T25) and finally at the end of surgery time (Tf). The results were analyzed by SPSS software version 23, and a Results: The mean arterial pressure during surgery between T3 and T9 and the mean heart rate in times of T3-T8 in the intervention group were higher than in the control group, and this difference was statistically significant ( Conclusion: This study showed the effectiveness of the prescription of 5 mg ephedrine two minutes before changing from the lithotomy position to the supine in maintaining hemodynamic stability, reducing hypotension, bradycardia, nausea, and vomiting, and the amount of prescribed ephedrine, atropine, and ondansetron.
