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
rationaleChronic patellar tendon rupture with complete tendon loss is difficult to reconstruct when primary repair is impossible. We report reconstruction using an ipsilateral peroneus longus (PL) autograft in a 4-strand "M-shaped" configuration with suture-anchor fixation and temporary cerclage augmentation. PATIENT CONCERNS: A 17-year-old male had progressive anterior knee pain, instability, and inability to actively extend the left knee for 2 years after trauma. DIAGNOSES: Examination showed patella alta, a palpable infrapatellar gap, and complete loss of active extension. Radiographs showed an Insall-Salvati ratio of 1.28. Magnetic resonance imaging confirmed chronic complete patellar tendon rupture without a repairable stump.
interventionsA 21-cm ipsilateral PL autograft was folded into a 4-strand construct and anchored to the inferior patella and tibial tubercle. Patellar height was deliberately overcorrected, and a transpatellar-tibial cerclage wire protected the reconstruction during staged rehabilitation. OUTCOMES: At 1 year, after wire removal, the Insall-Salvati ratio was 1.08. The patient regained full active extension without lag, near-full flexion, and recreational activity participation without pain or donor-site morbidity. Asymptomatic wire breakage occurred at 6 months. LESSONS: A multi-strand PL autograft with anchor fixation and temporary cerclage augmentation may restore patellar height and extensor function in chronic patellar tendon rupture with complete tendon loss.
