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
Purpose: The aim of this study was to investigate the prevalence of the deep lateral femoral notch sign (DLFNS) in skeletally immature patients with anterior cruciate ligament (ACL) injuries and its potential association with trauma-related and clinical factors. Methods: A total of 87 skeletally immature patients with ACL injuries and a minimum follow-up of 1 year were included and matched based on sex and skeletal age with 44 controls. The presence of the DLFNS, defined as a notch depth of >1.5 mm, was assessed on MRI. Intra- and inter-observer reliability were calculated, and prevalence was determined. Associations between the DLFNS and trauma mechanism, trauma-related bone lesions, concomitant injuries, clinical instability, and treatment at both baseline and follow-up were assessed using Fisher's exact tests. Results: The prevalence of DLFNS was 11.5% (10/87) among skeletally immature patients with ACL injuries compared to 0% (0/44) in controls ( Conclusion: The prevalence of the DLFNS in skeletally immature patients with ACL injuries was 11.5%. When present, the DLFNS was associated with overall concomitant knee injuries and primary ACL reconstruction. The DLFNS may therefore be an important sign to take into consideration on the primary MRI in skeletally immature patients with ACL injuries. Level of Evidence: Level III.
