Effect of transversus abdominis plane block on postoperative pain after nephrectomy: a systematic review.
Synthesis in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To systematically evaluate the effect of transversus abdominis plane block (TAPB) on postoperative analgesia after nephrectomy. Methods: A computerised search was conducted to identify randomised controlled trials (RCTs) evaluating TAPB for postoperative analgesia after nephrectomy from database inception to 31 January 2026 in the Cochrane Library, PubMed, Embase, Web of Science, China Biomedical Literature Service, Wanfang Data, and the China National Knowledge Infrastructure. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was performed using Review Manager 5.4. The quality of evidence was graded using the GRADEpro system, and publication bias for endpoint indicator was assessed using Stata 17.0. Results: Ten RCTs involving a total of 639 patients were included. The meta-analysis showed that, compared with the control group, the TAPB group demonstrated a significant reduction in intravenous morphine equivalents at 24-hour postoperative [MD = -16.67, 95% CI (-25.57, -7.77), Conclusion: Except for the absence of significant differences in resting pain scores at 2 and 4 hours postoperative, TAPB might reduce postoperative pain after nephrectomy, decreased postoperative opioid consumption, lowered postoperative pain scores, and reduced gastrointestinal adverse reactions.
