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
purposeThe aim of the present study was to assess the long-term outcomes of the treatment of chronic ankle instability (CAI) with a four-step protocol.
methodsFifty-four patients with isolated anterior talo-fibular ligament (ATFL) lesion suffering from CAI who underwent surgical treatment between 2000 and 2009 were assessed. All the patients underwent a four-step protocol including synovectomy, debridement of ATFL lesion borders, capsular shrinkage, and 21-day immobilization and nonweightbearing. Median age at surgery was 31.6 years (18-48). Patients were examined preoperatively and at follow-up. Clinical assessment included the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scoring system, Karlsson-Peterson score, Tegner activity level, and objective examination comprehending range of motion (ROM) and manual laxity tests.
resultsAOFAS (preoperative, 64.8; postoperative, 92.4; p < 0.001) and Karlsson-Peterson score (preoperative, 62.5; postoperative, 88.8; p < 0.001) significantly improved after a median 11 years follow-up (7-16 years). Similarly median Tegner activity level significantly increased at follow-up compared to pre-operatory status (6.0 and 4.0 respectively, p < 0.001). Objective examination documented a statistically significant improvement in terms of ankle stability compared to pre-operative manual laxity tests, with negative anterior drawer test observed in 48 (88.9%) patients (p < 0.001). Sagittal ROM was full in 50 patients (92%). Nine patients had subsequent ankle sprains (15.6%), two patients required further surgery, while seven were treated conservatively. No major complications were reported.
conclusionSatisfying subjective and objective clinical outcomes in selected patients with isolated ATFL lesion suffering from CAI were reported with a treatment protocol including arthroscopic synovectomy, debridement of ATFL remnants, capsular shrinkage, and immobilization. These findings are of clinical relevance because they provide a suitable minimally invasive method for the treatment of mild to moderate ankle instability. LEVEL OF EVIDENCE: Level IV.
