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
Patellar tumors are rare. However, aggressive tumors such as giant cell tumors of the bone can cause large defects. The treatment of large patellar defects remains controversial. This case report presents the results of a new reconstruction method applied to a 40-year old man with a large patellar defect due to a giant cell tumor of the bone, along with an 8-year follow-up. The defect was reconstructed using a handmade neopatella. This neopatella was created using a bony Achilles tendon allograft and patellar polyethylene. Postoperatively, good results were achieved without hindering the patient's ability to farm. These excellent functional results were still maintained at the eighth year of follow-up. This reconstruction method allowed for the restoration of extension strength by re-establishing the lever arm of the extensor mechanism. The main advantages of this method compared to fresh-frozen allografts are the longer shelf life of the materials used and the modularity of both patellar thickness and patellar height. This method may be a new and promising alternative to fresh frozen quadriceps-patella-patellar tendon allografts in the reconstruction of large patellar defects. Cite this article as: Özgezmez FT.
