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
Introduction: Patellar tendon rupture is an uncommon injury that may progress to a chronic or neglected state when initial diagnosis and treatment are delayed. Case Report: We report the case of a 17-year-old male who sustained a cut-laceration injury over the right knee that was sutured primarily elsewhere, following which he developed progressive instability and inability to actively extend the knee. Imaging revealed patella alta with a complete patellar tendon rupture. The patient underwent reconstruction using a modified Ecker's technique with semitendinosus and gracilis autografts passed through single tibial and patellar tunnels in figure-of-eight and figure-of-seven configurations, respectively, to restore the extensor mechanism. Post-operative rehabilitation involved staged mobilization with a hinged knee brace and progressive range-of-motion exercises. At 1-year follow-up, the patient had regained functional knee flexion, returned to daily activities, and demonstrated only minimal residual extension lag. Conclusion: This case highlights the effectiveness of hamstring autograft reconstruction using a biologic tension-band-like configuration for chronic neglected patellar tendon ruptures, allowing stable fixation, early rehabilitation, and satisfactory functional recovery.
