Efficacy of Ultrasound-Guided Thoracic Paravertebral Block on Postoperative Quality of Recovery in Patients Undergoing Percutaneous Nephrolithotomy: A Randomized Double-Blind Placebo-Controlled Trial.
Trial report in Journal of pain research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Purpose: This study aimed to examine the effectiveness of ultrasound-guided thoracic paravertebral block on postoperative quality of recovery in patients undergoing percutaneous nephrolithotomy. Patients and Methods: In this randomized, double-blind, placebo-controlled trial, we enrolled patients scheduled for unilateral percutaneous nephrolithotomy. Patients were randomly allocated to receive thoracic paravertebral block either with 20 mL of 0.5% ropivacaine (PVB group) or an equal volume of saline (control group). The primary outcome was the quality of patient recovery at 24 h postoperatively, assessed using the 15-item Quality of Recovery scale. The secondary outcomes included the area under the curve of pain scores over time, time to first rescue analgesia, and postoperative 24 h morphine consumption. Results: We analyzed the data of 70 recruited participants. The median Quality of Recovery-15 score at 24 h postoperatively was 127 (interquartile range, 117-133) in the PVB group, which was significantly higher than 114 (interquartile range, 109-122) in the control group, with a median difference of 10 points (95% confidence interval, 5-14; Conclusion: Preoperative ultrasound-guided single injection of thoracic paravertebral block with ropivacaine improved the postoperative quality of recovery and analgesia in patients undergoing percutaneous nephrolithotomy.
