The Effect of Ultrasound-Guided Multipoint Thoracic Paravertebral Nerve Block in Metabolic and Bariatric Surgery (MBS): A Prospective Randomized Controlled Trial.
Trial report in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe study aims to compare the effects of multipoint thoracic paravertebral block combined with general anesthesia to general anesthesia alone in metabolic and bariatric surgery (MBS).
methodsA total of 80 patients were randomly assigned in a 1:1 ratio to the Thoracic Paravertebral Block group (TPVB group) and the General Anesthesia group (GA group). The TPVB group received multipoint TPVB combined with GA bilaterally at the T6 and T9 levels, while the GA group received only GA. The primary outcome was the quality of recovery scores (QoR-15) at 24 h and 48 h postoperatively, while secondary outcomes included NRS scores at different time points postoperatively, intraoperative sufentanil consumption, cumulative consumption of postoperative rescue analgesics, postoperative hospital length of stay, postoperative extubation time, time to first flatus and urination, and complications related to the nerve block.
resultsThe QoR-15 scores at 24 h and 48 h were significantly higher in TPVB group compared with GA group [24 h: 127.0(124.0,129.0) vs 113.0(109.0,115.0), 48 h: 139.0(137.0,141.0) vs 132.5(126.0,135.0) (P < 0.001)]. The NRS scores in the TPVB group were significantly lower than the GA group at different time points postoperatively (P < 0.05). The intraoperative sufentanil use was significantly less in the TPVB group and the TPVB group required less rescue analgesia (P < 0.05). The extubation time and first flatus time were significantly shorter in the TPVB group than in the GA group (P < 0.05).
conclusionMultipoint TPVB improves the quality of postoperative recovery in patients undergoing metabolic and bariatric surgery (MBS) and reduces postoperative pain and opioid use.
