lnfraspinatus-teres minor interfascial block combined with periarticular infiltration versus periarticular infiltration analgesia alone for postoperative analgesia in patients undergoing arthroscopic shoulder surgery: protocol for a randomized controlled clinical trial.
Article in Trials, 2025. 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
backgroundAlthough interscalene nerve block is considered as the standard analgesic method for arthroscopic shoulder surgery, it is not indicated for patients with respiratory comorbidity. Periarticular infiltration is usually used for postoperative analgesia following orthopedic surgery, with uncertain analgesic effects. Infraspinatus-teres minor interfascial (ITM) block is an innovative method used in arthroscopic shoulder surgery. We supposed that ITM block combined with periarticular infiltration could provide adequate analgesia for patients undergoing arthroscopic shoulder surgery.
methodsThis is a randomized, parallel-controlled, prospective, single-center study. Fifty-six patients scheduled for arthroscopic shoulder surgery will be randomized into two groups: ITM block combined with periarticular infiltration group (ITM group) and periarticular infiltration group (PAI group). Periarticular infiltration will be administered to all patients following surgery. The primary outcome is the time from the end of surgery to the first press of the patient-controlled analgesia pump (PCA) in the two groups. Secondary outcomes are the following: intraoperative remifentanil and propofol consumption, hemodynamic changes, VAS scores, frequency of PCA compression, remedy analgesic consumption, length of hospital stay, patients satisfaction score, and adverse reactions. DISCUSSION: This study will demonstrate the analgesic efficacy of ITM block combined with periarticular infiltration in arthroscopic shoulder surgery.
