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.

Abstract
Background: Although bone marrow stimulation (BMS) is believed to promote rotator cuff healing, there is no comparison of clinical outcomes and structural integrity between different BMS techniques in patients undergoing arthroscopic rotator cuff repair (ARCR). Purpose/Hypothesis: The purpose of this study was to compare the clinical outcomes and structural integrity between BMS inside the rotator cuff footprint area ("greenhouse" technique) and BMS outside the rotator cuff footprint area ("crimson duvet" technique). It was hypothesized that the new "greenhouse" technique would provide better clinical outcomes and structural integrity at short-term follow-up. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: This study included 60 patients who underwent ARCR using the "greenhouse" technique or "crimson duvet" technique (n = 30 per group). Functional outcomes at 24 months postoperatively were assessed including the ASES (American Shoulder and Elbow Surgeons) score, CMS (Constant-Murley score), UCLA (University of California, Los Angeles) score, SST (Simple Shoulder Test), VAS (visual analog scale) for pain, and range of motion consisting of forward elevation, external rotation, and internal rotation. The minimal clinically important difference, patient acceptable symptom state, substantial clinical benefit, and maximum outcome improvement were also compared between the 2 groups. Structural integrity was evaluated by magnetic resonance imaging at 2 years postoperatively and compared between the 2 groups. Results: All functional outcomes improved significantly compared with preoperatively in both groups at the last follow-up (all Conclusion: In ARCR, both the "greenhouse" and "crimson duvet" techniques exhibited significant functional improvement in patients with rotator cuff tears. The new "greenhouse" technique provided comparable clinical outcomes and structural integrity compared with the traditional "crimson duvet" technique at short-term follow-up.
