Extracapsular subcutaneous endoscopic treatment for refractory lateral epicondylalgia: technique, retrospective results, and prognostic factors.

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
backgroundThe extracapsular subcutaneous endoscopic treatment is a new and under-researched approach to the endoscopic treatment of refractory lateral epicondylalgia. We aimed to introduce the techniques of the method and the mid-long term clinical effects. Furthermore, we intended to identify demographic and surgical-related factors correlated with prognosis of extracapsular subcutaneous method.
methodsPatients with a minimum of 6 months of conservative treatment for lateral epicondylalgia were recruited from March 2012 to July 2018. Key surgical techniques including microfracture and endoscopic suture were used. Visual analog scale (VAS), Mayo Elbow Performance Score (MEPS), and Disability of Arm (Shoulder and Hand, DASH) scores were used to evaluate clinical results. Univariable analysis and multivariable logistic regression were used to analyze effects of demographic characteristics and treatment techniques on prognosis.
resultsSeventy-eight patients were treated with modified subcutaneous extracapsular surgery. No serious complications such as neurovascular injury or infection occurred. Postoperative VAS, MEPS, and DASH scores significantly improved (P<0.001). Age was associated with prognosis regarding VAS score (P=0.023). Older age was an independent relevant factor for poor prognosis regarding VAS score (OR =0.914, 95% CI: 0.842-0.993, P=0.033), and microfracture during surgery related to poor prognosis for DASH score (OR =0.056, 95% CI: 0.004-0.783, P=0.032). Plaster fixation was an independent factor related to good prognosis regarding DASH score (OR =11.156, 95% CI: 1.009-123.363, P=0.049).
conclusionsExtracapsular subcutaneous method of refractory lateral epicondylalgia has satisfactory and stable clinical results with high safety. Techniques of extracapsular method include debridement, microfracture, and tendon suture under endoscope. Young age, no microfracture, and postoperative plaster fixation were associated with good long-term prognosis.
