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
purposeThis study aims to refine management strategies for malunion and nonunion of Hoffa fractures, as these rare complications present significant clinical challenges.
methodsWe conducted a case series involving seven patients with Hoffa fracture complications, including four cases of malunion and three cases of nonunion. Each patient underwent individualized surgical treatment, depending on the nature of their complication. Treatment strategies varied from intra-articular osteotomies for malunions to revision surgery or total knee arthroplasty for nonunions. Postoperative outcomes were monitored, with follow-up ranging from 1 to 15 years (mean follow-up time was 6.7 years).
resultsIn all malunion cases, intra-articular osteotomies restored the articular surface, leading to improved function and bone healing. In nonunion cases, two patients with non-reconstructible nonunions underwent total knee arthroplasty, while one patient achieved union with surgical revision. Overall, six out of seven patients showed significant functional improvements post-surgery, although some experienced mild residual pain or deformities.
conclusionThe management of malunion and nonunion in Hoffa fractures remains challenging, but the individualized strategy based on fracture type and patient-specific factors leads to favourable outcomes. The proposed treatment algorithm provides a useful framework for orthopaedic trauma surgeons in addressing these complications, with emphasis on stable fixation, early intervention, and personalized surgical planning.
