Postoperative analgesic efficacy of intertransverse process block vs. erector spinae plane block in total laparoscopic hysterectomy: a randomized double-blind trial.
Article 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
Background: Due to multiple factors, patients will experience significant postoperative pain following laparoscopic total hysterectomy (TLH), predominantly manifesting as visceral pain. For the first time, we compared the analgesic effects of intertransverse process block (ITPB) and erector spinae plane block (ESPB) in patients undergoing TLH. We hypothesized that ITPB would further reduce the perioperative opioid dosage and improve visceral pain in TLH patients when compared with ESPB. Methods: This research included 66 patients (18-65 years-of-age) undergoing TLH under general anesthesia. Patients were assigned by randomization to either an ITPB or ESPB group. Ultrasound-guided bilateral intertransverse process blocks at T10-11 were performed for patients in the ITPB group, with 0.375% (20 mL) ropivacaine per side. For the ESPB group, we performed bilateral ultrasound-guided ESPB at the T10 level with 0.375% ropivacaine (20 mL) per side. All patients received total intravenous anesthesia guided by the bi-spectral index (BIS). The primary outcome included total opioid use, expressed as morphine equivalents, within the first 24 h following surgery. Results: Patients in the ITPB group required significantly lower intraoperative remifentanil doses (mean difference: -328.0 μg, 95% CI: -395.2 to -260.9, Conclusion: Compared with ESPB, ITPB more effectively reduced perioperative opioid consumption and provided superior and sustained postoperative visceral analgesia for patients undergoing total laparoscopic hysterectomy. In addition, ITPB was associated with improved short-term postoperative recovery quality. In future, studies need to elucidate the underlying mechanisms of ITPB and optimize the volume and concentration of local anesthesia for administration.
