Efficacy of transversus abdominis plane block for gastric surgery: a meta-analysis.
Synthesis in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMultimodal analgesia is an important component of Enhanced Recovery After Surgery (ERAS). Transversus abdominis plane (TAP) block helps achieve this pain management in various types of surgeries. To evaluate the efficacy of TAP block versus non-TAP approaches for postoperative pain management and recovery after gastric surgery.
methodsA systematic literature search across four databases (Cochrane, Embase, Web of Science, PubMed) until February 2024 identified relevant randomized controlled trials (RCTs) evaluating TAP block in gastric surgery. Two independent reviewers screened studies, extracted data, and assessed analyses. PRIMARY OUTCOME: postoperative pain scores. SECONDARY OUTCOMES: postoperative opioid consumption, hospital stay, time to ambulation, and time to flatus.
resultsTwelve RCTs involving 841 participants were included. Compared to non-TAP, the TAP group demonstrated significantly lower visual analog scale (VAS) pain scores at 1, 3, 6, 12, 24, and 48 h postoperatively (WMD range: -0.62 to -0.97). Time to first ambulation (SMD - 0.46; 95% CI: -0.92, 0.00) and first flatus (WMD - 5.17; 95% CI: -8.58, -1.77) were shorter in the TAP group. Postoperative opioid consumption was reduced with TAP (WMD - 1.89; 95% CI: -2.41, -1.37), with no difference in hospital stay between groups.
conclusionTAP block effectively relieves pain after gastric surgery, decreases postoperative morphine requirements, and modestly shortens bed rest duration while promoting intestinal function recovery. However, it does not significantly affect the overall hospital length of stay.
