A systematic review and meta-analysis of the effects of general anesthesia combined with continuous paravertebral block in breast cancer surgery and postoperative analgesia.

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
backgroundThis study aimed to compare the effects of general anesthesia (GA) combined with continuous paravertebral block (CPVB) in breast cancer surgery via systematic review and meta-analysis, in order to provide a theoretical basis for the clinical use of CPVB surgical analgesia.
methodsA search of the PubMed, Embase, Medline, Ovid, Springer, and Web of Science databases was conducted to screen clinical trials on GA + CPVB for breast cancer surgery published before December 31, 2020. The Cochrane Handbook for Systematic Reviews of Intervention 5.0.2 was adopted for bias risk assessment, and Review Manager 5.3 software (RevMan, The Cochrane Collaboration, http://tech.cochrane.org/revman) was applied for meta-analysis of the literature.
resultsA total of 15 studies that satisfied the requirements were included, involving a total of 1,435 research subjects. The results of our meta-analysis showed the following: the visual analogue scale (VAS) score of the observation group (group A) was significantly reduced [mean difference (MD) =-0.68; 95% confidential interval (CI): -1.04 - -0.33; Z=3.80; P=0.0001]; the level of monocyte chemoattractant protein -1 (MCP-1) was notably decreased (MD =-18.64; 95% CI: -29.68 - -7.61; Z=3.31; P=0.0009); the level of tumor necrosis factor-α (TNF-α) was markedly lower (MD =-1.89; 95% CI: -2.66 - -1.13; Z=4.87; P<0.00001); the interleukin-6 (IL-6) level was obviously reduced (MD =-12.10; 95% CI: -19.22 - -4.99; Z=3.33; P=0.0009); and the incidence of postoperative adverse reactions was substantially decreased (MD = 0.16; 95% CI: 0.07-0.36; Z=4.47; P<0.00001). Compared with group B, the differences of the above five indicators showed statistical significance. In addition, the heart rate (HR) (MD =-1.56; 95% CI: -6.20 - 3.08; Z=0.66; P=0.51), mean arterial pressure (MAP) (MD = 4.66; 95% CI: -0.12 -9.43; Z=1.91; P=0.06), Ramsay score (MD =0.44; 95% CI: -0.06-0.93; Z=1.73; P=0.08) of patients in group A showed no statistical differences compared to group B.
conclusionsGA + CPVB applied to breast cancer surgery for analgesia can reduce the levels of MCP-1, TNF-α, and IL-6 in patients, thereby providing good postoperative analgesia. Therefore, GA + CPVB could effectively reduce the incidence of pain and adverse reactions in patients, and is effective for analgesia in breast cancer surgery.
