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
Purpose: This study aimed to compare the risk of vagal reflex during microsurgical subinguinal varicocelectomy (MSV) under general anesthesia (GA) with or without additional local anesthetic (LA) spermatic cord block (SCB). Method: A single-center randomized controlled trial was conducted between January 2022 and June 2023.300 patients with left-sided grade Ⅲ varicocele were randomly divided into two groups: SCB group (n = 153) and control group (n = 147)（computer-generated random numbers list）. During MSV under GA, the SCB group was given of ropivacaine for SCB before pulling the spermatic cord, while the control group was directly lifted. The primary outcome was the reduction in the lowest heart rate in the SCB group as compared with the control group during spermatic cord traction (SCT). Secondary outcomes included the reduction in the lowest blood pressure in the SCB group as compared with the control group; and the reductions in the lowest heart rate and lowest blood pressure as compared with baseline during SCT. The number of times that surgery and medications were suspended because of symptomatic reflex bradycardia was also recorded. Adverse events were also recorded as secondary outcomes. Result: Five patients in the SCB group and 10 patients in the CG were excluded. The lowest heart rate and systolic blood pressure during SCT in the SCB group and the control group were significantly lower than the baseline values (P < 0.05). However, the decrease in the SCB group (70-73bpm VS 108-115 mmHg) was milder than that of the control group（66-72 bpm VS 105-114 mmHg）(P < 0.05). The number of surgeries and medication pauses due to symptomatic reflex bradycardia during surgery was significantly lower in the SCB group (2 VS 1) than in the control group (9 VS 7) (P < 0.05). Conclusion: SCB can effectively reduce the vagal reflex caused by pulling the spermatic cord during MSV, and reduce the risk of anesthesia and surgery.
