No Difference Between Open and Arthroscopic ATFL Repair, Both Yielding Clinically Significant Improvement in Chronic Ankle Instability: A Randomized Controlled Trial.
Article in Orthopaedic journal of sports medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02998333 (Does Arthroscopic Anatomic Repair of the Anterior Talofibular Ligament Provide Better Functional Outcome Compared to Open Anatomic Repair in Patients With Chronic Ankle Instability), which is not on this map.

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: Lateral ligament repair is a reliable surgical approach for the treatment of chronic ankle instability (CAI). Although the open technique has shown success over time, technological advancements have enabled the increasing use of arthroscopic techniques, with the expectation of improving results. The objective of the current trial was to compare the results of open and arthroscopic anterior talofibular ligament (ATFL) repair in patients with CAI. Hypothesis: Arthroscopic anatomic repair would lead to superior functional outcome as measured by the Foot and Ankle Outcome Score (FAOS) compared with open anatomic repair. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Patients at 6 participating sites were included if they were age 16 years or older, had a history of ankle inversion sprain, had symptoms ≥6 months, and had mechanical ankle instability. Randomization was performed over open and arthroscopic ATFL repair, with or without retinacular augmentation. Both procedures were performed using all-suture anchors and corresponding instrumentation. The primary outcome measure was functional outcome as measured by the FAOS at 24 months of follow-up. Results: A total of 41 patients were included: 21 patients in the open repair group and 20 patients in the arthroscopic repair group. The mean ± SD age of the patients at the time of surgery was 32 ± 13 years. No statistically significant difference was found between treatment groups for any of the FAOS subscales at any of the follow-up intervals. Both groups showed statistically significant score improvements across all FAOS subscales ( Conclusion: Open and arthroscopic ATFL repairs equally achieved statistically significant improvement in functional outcome and effectively addressed functional and mechanical ankle instability. Registration: ClinicalTrials.gov database (reference NCT02998333) and the Dutch trial registry (NL55707.018.16).
