Analgesic efficacy of ultrasound-guided transversus abdominis plane block for laparoscopic gynecological surgery: a randomized controlled trial.
Article in Anesthesia and pain medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThis study aimed to determine whether ultrasound-guided transversus abdominis plane (TAP) block is more effective in reducing postoperative pain and analgesic consumption than local anesthetic infiltration (LAI) at the port site for elective laparoscopic gynecological surgeries.
methodsEighty patients with the American Society of Anesthesiologists status I/II undergoing laparoscopic gynecology surgery were enrolled for this randomized control trial. After general anesthesia was administered, patients in group C received LAI at each port site, and patients in group T received bilateral ultrasound-guided TAP. Postoperative pain was assessed at time intervals of 1/2, 2, 4, 6, 8, and 24 h using the numeric pain scale (NPS). Clinical metrics such as postoperative analgesic diclofenac consumption, need for rescue fentanyl, nausea-vomiting scores, and antiemetic requirements were also recorded.
resultsSeventy-four patients were included in the final analysis. Postoperatively, patients in group T had significantly lower NPS than those in group C (P < 0.05). The highest difference in the postoperative NPS was observed at 2 h (median [1Q, 3Q]; group C = 3 [2, 4]; group T = 1 [0, 2]; P < 0.001). A statistically significant difference was observed in the frequency of diclofenac (75 mg intravenous) requirement between the groups (P = 0.010). No significant difference was observed between the groups in need of rescue fentanyl or antiemetic and the nausea-vomiting scores.
conclusionsIn patients undergoing laparoscopic gynecological surgery, ultrasound-guided TAP block provided greater postoperative analgesic benefits in terms of lower NPS and reduced analgesic requirements than port site LAI.
