1 · What the graph read from it

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.

2 · The registry

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

purposeThis prospective randomized study compared the clinical outcomes of patients undergoing arthroscopic repair for partial-thickness bursal-side rotator cuff tears (PT-BRCTs) using the double-locking loop stitching technique (DLLST) versus traditional conversion-to-full-thickness repair techniques.

methodsThe study included 110 patients with PT-BRCTs exceeding 50% of tendon thickness. They were randomly assigned to two groups during surgery. Ninety-four patients completed follow-up (Group I: DLLST, n = 43; Group II: traditional repair, n = 51). Clinical outcomes, including range of motion (ROM), visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant score, and modified SF-12 quality-of-life scores, were assessed preoperatively, at 3 months, and final follow-up. Postoperative MRI evaluated tendon integrity.

resultsBoth groups demonstrated significant improvements in all clinical parameters (P < 0.05). At final follow-up, Group I exhibited superior ASES (91.25 ± 2.88 vs. 89.95 ± 3.24, P = 0.042) and Constant scores (91.19 ± 2.73 vs. 90 ± 2.76, P = 0.040), along with faster pain reduction at 3 months (VAS: 2.19 ± 1.33 vs. 2.67 ± 0.99, P = 0.023). No significant differences were observed in SF-12 scores (P > 0.05). MRI confirmed complete tendon healing in all cases.

conclusionBoth techniques provided satisfactory functional recovery and pain relief for PT-BRCTs exceeding 50% of tendon thickness. However, DLLST achieved faster functional restoration while preserving tendon integrity, suggesting its potential as a biomechanically advantageous alternative.
