Preoperative external rotation lag sign doesn't diminish the efficacy of arthroscopy-assisted lower trapezius tendon transfer in posterosuperior irreparable rotator tears.

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
Introduction: The purpose of this study is to compare the clinical outcomes according to preoperative external rotation (ER) status, comparing patients with a preoperative ER lag sign (ERL group) to those with preoperative no ER lag sign (non-ERL group) in arthroscopy-assisted lower trapezius tendon transfer (aLTT) for posterosuperior rotator cuff tears (PSIRCTs). Methods: This retrospective study reviewed 107 patients who were treated with aLTT for PSIRCTs between 2017 and 2022. The patients were divided into ERL group (n = 20) and non-ERL group (n = 87). Clinical outcomes were evaluated with shoulder pain, patients-reported clinical scores, active range of motion (aROM) and strength of aROM. Radiologic outcomes were evaluated with acromiohumeral distance and Hamada classification. The relationship between trophicity of teres minor (Tm) and clinical outcomes was evaluated. Results: Preoperative patients-reported clinical scores, aROM, and strength of aROM were significantly lower in ERL group. Although a significant improvement of postoperative pain score, patients-reported clinical scores, aROM, and strength of aROM was observed in both groups, these postoperative outcomes were significantly lower in ERL group. However, the mean improvement of Constant score, University of California, Los Angeles (UCLA) score, and activities of daily living that require active external rotation (ADLER) score, forward elevation (FE), abduction, external rotation (ER) were significantly higher in ERL group than that of non-ERL group. Moreover, there was a significant correlation between Tm trophicity and postoperative Constant, UCLA, American Shoulder and Elbow Surgeons score, ADLER, FE and ER. Conclusion: aLTT can be a reliable treatment option and should be considered as primary joint-preserving treatment option for patients with PSIRCTs regardless of preoperative ER lag sign. Level of study: Level IV.
