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
Background: Anterior cruciate ligament (ACL) primary repair (ACLPR) has been proposed as a treatment option for select patients with proximal ACL tears. However, long-term data are imperative to validate the utility of this technique. Purpose: To determine the long-term incidence of posttraumatic osteoarthritis (PTOA) and clinical outcomes after arthroscopic ACLPR. Study Design: Case series; Level of evidence, 4. Methods: Prospective data were collected on consecutive patients with modified Sherman type 1 ACL tears who underwent ACLPR between 2008 and 2013. Inclusion required minimum 10-year follow-up. Standardized radiographs of both knees were obtained preoperatively and at 10-year follow-up to assess PTOA as determined by Kellgren-Lawrence (KL) grade and minimal joint space width. Clinical outcomes included repair failure (anterior tibial translation side-to-side difference (ATT SSD) ≥3 mm, grade ≥2 Lachman, grade ≥2 pivot-shift test and/or subjective instability) and reoperation rates, ATT SSD, International Knee Documentation Committee (IKDC) Subjective Knee Form, Lysholm, Forgotten Joint Score-12 (FJS-12), ACL Return to Sport after Injury Survey (ACL-RSI), Tegner activity scale (Tegner), and Patient Acceptable Symptom State (PASS). Results: Outcomes were available for 16 of 18 eligible patients (median age at surgery, 40 years; 79% male) with a median follow-up of 11 years (IQR, 10-12 years). PTOA assessment revealed 42% (5/12) KL grade 0, 50% (6/12) grade 1, and 8% (1/12) grade ≥2. There were no significant differences in KL grading compared with preoperative ipsilateral values ( Conclusion: At minimum 10-year follow-up, a low incidence of clinically relevant radiographic osteoarthritis was observed in patients who underwent ACLPR. These patients can expect to experience a high rate of clinically significant outcome achievement, preserved knee stability, and an acceptable repair failure rate of 12.5% at long-term follow-up. While the present study provides meaningful insights, validation in larger cohorts remains essential.
