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 Total knee arthroplasty (TKA) is often associated with intense postoperative pain, which can delay mobilization and hinder recovery. While motor-sparing blocks such as the femoral triangle block (FTB) and adductor canal block (ACB) are commonly used, both offer incomplete analgesic coverage. To overcome these limitations, the dual subsartorial block (DSB) was introduced as a procedure-specific, motor-sparing technique that combines and modifies FTB and ACB into a dual-injection approach for enhanced efficacy. Objective The objective of this study is to compare the analgesic efficacy, motor-sparing effect, opioid-sparing potential, and patient satisfaction among three regional analgesia (RA) techniques, FTB, ACB, and DSB, in patients undergoing TKA. Methods This prospective, double-blind, monocentric trial enrolled 120 patients undergoing unilateral primary TKA, randomized equally into FTB, ACB, or DSB groups (n = 40 each). All patients received standardized spinal anesthesia followed by the assigned ultrasound-guided block. The primary outcome was postoperative quadriceps strength. Secondary outcomes included visual analog scale (VAS) pain scores, rescue opioid use, pain location mapping, patient satisfaction, and block duration. Results Quadriceps strength was preserved in all groups. DSB showed significantly better static and dynamic pain control (p < 0.001), with zero opioid use compared to minimal use in FTB and highest use in ACB. Pain mapping revealed incomplete coverage with ACB, particularly at upper incision sites. DSB provided the longest block duration (>24 hours) and the highest satisfaction scores. Conclusions DSB, which strategically integrates and modifies FTB and ACB, offers superior, comprehensive, and motor-sparing analgesia. Its enhanced anatomical precision and functional benefits suggest that DSB can be considered a reliable, procedure-specific RA technique with a strong potential to improve outcomes in modern TKA care pathways.
