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: The influence of patient demographics, associated meniscal injuries, and especially the time from injury to surgery on knee laxity before anterior cruciate ligament reconstruction (ACLR) remains insufficiently explored. Purpose: To identify factors associated with high-grade knee laxity before ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: Patients without concomitant ligament injuries who underwent primary ACLR at Capio Artro Clinic, Stockholm, Sweden, from January 2000 to December 2023 were identified. Demographic data (age and sex), concomitant medial or lateral meniscus injury, time from injury to surgery, and instrumented knee laxity were reviewed. The KT-1000 arthrometer (134 N) was used to evaluate anterior knee laxity preoperatively. High-grade laxity was defined as a side-to-side (STS) difference >5 mm (International Knee Documentation Committee grade C or D). A logistic regression analysis was used to evaluate whether age at surgery, sex, medial or lateral meniscus injury, and time from injury to ACLR were associated with high-grade preoperative knee laxity. Results: A total of 7759 patients (53.9% male) were included, of whom 1596 had high-grade knee laxity (STS difference >5 mm) preoperatively. Younger age (≤26 years) (OR, 1.19; 95% CI, 1.06-1.33; Conclusion: Age ≤26 years, medial meniscus injury, and delayed surgery (>6 months) were associated with high-grade knee laxity (STS difference >5 mm) before ACLR. To reduce the likelihood of knee laxity deterioration, ACLR should be performed within 6 months of the injury.
