Intertransverse process block versus subcostal transversus abdominis plane block in patients undergoing laparoscopic radical gastrectomy: a prospective randomized controlled trial.
Trial report in BMC anesthesiology, 2025. 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
backgroundLaparoscopic radical gastrectomy has been reported to be associated with substantial trauma and pain. This study compared the impact of ultrasound-(US)-guided, bilateral, double-injection intertransverse process block (ITPB) on postoperative analgesia with subcostal transversus abdominis plane block (TAPB) in patients who were undergoing laparoscopic radical gastrectomy.
methodsSixty-two patients who were undergoing laparoscopic radical gastrectomy surgery under general anesthesia were included. These patients were randomized to either the ITPB group or the TAPB group. Patients in the ITPB group received a double-shot US-guided bilateral ITPB at the thoracic level T6/7 and T9/10 level using ropivacaine (0.3%, 15 mL). Patients in the TAPB group received bilateral subcostal TAPB one injection per side using ropivacaine (0.3%, 30 mL). All patients used a BIS-guided combined intravenous and inhalation anesthesia. The primary outcome was defined as postoperative morphine-equivalent consumption during the first 24 h.
resultsThe study recruited 62 patients (31 in each group) for the analysis. A comparatively less postoperative opioid consumption was observed in the ITPB group compared with the subcostal TAPB group within the first 24 h postoperatively (mean [standard deviation-(SD)] morphine-equivalent dose): 27.8 (5.7) mg vs 31.2 (4.4) mg, P < 0.001. The ITPB group showed lower intraoperative opioid use, and statistical significantly lower scores at rest and coughing at 6, 24 h postoperatively. The time to first requiring rescue analgesia was longer in the ITPB group than the subcostal TAPB group (median [IQR]): 8.0 [8.0] vs 6.0 [6.0] h, P = 0.009. The patients in the ITPB group exhibited earlier independent movement, lower incidence of postoperative complications and higher levels of satisfaction (P = 0.021).
conclusionThis study showed that the double-shot bilateral ITPB could reduce opioids consumption and achieve longer and better pain relief. Additionally, it promoted early postoperative activity and improved patient satisfaction.
