Efficacy of Methylene Blue Thoracic Paravertebral Block in Postoperative Pain After VATS Lobectomy.
Article in Annals of thoracic surgery short reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Paravertebral block (PVB) is effective in controlling postoperative pain after video-assisted thoracoscopic surgery (VATS) lobectomy but is subject to a high rate of failure because of incorrect site of injection. We compared methylene blue PVB with thoracic epidural anesthesia (TEA) for postoperative pain after VATS lobectomy. Methods: We conducted a prospective randomized trial of patients undergoing VATS lobectomy; 120 patients were randomly assigned to the PVB or TEA group. The end points were postoperative pain at 1 hour, 12 hours, 24 hours, and 48 hours; time to perform TEA and PVB; opioid consumption; and postoperative outcomes. Results: PVB was associated with reduction of local anesthesia time ( Conclusions: PVB with methylene blue is as effective as TEA for controlling postoperative pain. Methylene blue use could help reduce PVB failure.
