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
Purpose: To investigate the clinical characteristics of postoperative subacromial impingement syndrome (SIS) in elderly patients undergoing arthroscopic rotator cuff repair (RCR) and to analyze its association with mid- to long-term postoperative functional recovery. Methods: A retrospective analysis was conducted on the clinical data of 150 elderly patients who underwent RCR between January 2023 and January 2025. Patients were stratified into an impingement group (n = 32) and a non-impingement group (n = 118) based on the presence of SIS at 3 months postoperatively. Preoperative baseline characteristics, surgery-related variables, and postoperative outcomes including the Constant-Murley Shoulder Score (CMS), the University of California, Los Angeles Shoulder Score (UCLA), and the Visual Analog Scale for pain (VAS) were compared between the two groups at 3, 6, and 12 months after surgery. Results: At 3 months postoperatively, the incidence of SIS was 21.33% (32/150). The affected patients mainly presented with aggravated shoulder pain during abduction and forward flexion, with 100% positive Neer impingement test and 90.63% positive Hawkins impingement test, and some patients had audible clicking during shoulder movement. At 3, 6, and 12 months after surgery, CMS and UCLA scores were significantly lower in the impingement group than in the non-impingement group, while VAS scores were significantly higher (all Conclusion: The incidence of SIS after RCR in elderly patients is relatively high, and the postoperative SIS in this population is characterized by aggravated shoulder pain during abduction and forward flexion, positive Neer and Hawkins impingement tests, and occasional audible clicking during shoulder movement. Postoperative SIS was significantly associated with poorer shoulder functional recovery and delayed pain relief in elderly patients undergoing arthroscopic rotator cuff repair.
