The Effect of Transversus Abdominis Plane Block for Analgesia in Patients Undergoing Liver Transplantation: A Systematic Review and Meta-Analysis.
Review in Turkish journal of anaesthesiology and reanimation, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveUltrasound-guided regional anaesthesia using transversus abdominis plane (TAP) block is a newer and safer method that can be used in patients undergoing liver transplant surgeries. This systematic review and meta-analysis was done to quantify the analgesic potential and opioid-sparing capability of TAP block in these patients.
methodsThe studies comparing TAP-block to conventional analgesic regimens for liver transplant were searched. The studies evaluating the comparative 24-h morphine consumption during postoperative period in patients undergoing liver transplant surgeries were searched and included as the primary outcome in the analysis.
resultsWe found two randomised controlled trials and two retrospective studies that on meta-analysis showed that TAP block group had significantly lower requirement of morphine (WMD=27.59 mg; 95% CI: 33.47-21.70) at 24 h for pain mitigation. Also, postoperative nausea and vomiting was lower (RR=0.76; 95% CI: 0.47-1.22) but not statistically significant.
conclusionUltrasound-guided TAP block provides postoperative analgesic efficacy in patients undergoing liver transplant surgeries. This study was registered in International prospective register of systematic reviews [PROSPERO: CRD42018094595].
