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 was designed to analyze the relationship between changes in posterior tibial slope and the absence or presence of lateral hinge fracture, diagnosed in the sagittal and axial planes, as well as the coronal plane, by computed tomography (CT) following opening wedge high tibial osteotomy (HTO).
methodsThis study involved 55 patients (55 knees) undergoing opening wedge HTO for primary medial osteoarthritis. Lateral hinge fractures were evaluated on CT scans according to the Takeuchi classification and were also classified as subtypes A, B, and C, depending on anterior, posterior, and both anterior and posterior cortical disruptions, respectively, as determined by the sagittal and axial planes of CT scans which corresponded to the fracture line visible on coronal CT scans.
resultsOf the 55 knees, 23 were found on postoperative CT scans to have lateral hinge fractures. All 23 were classified as Type I, with 11, 12, and 0 being subtypes A, B, and C, respectively. Mean change in posterior tibial slope from 3 weeks postoperatively to last follow up in subtype B was significantly greater than in subtype A (2.5° vs 0.2°, P = 0.008) and in knees without hinge fracture (2.5° vs 0.1°, P = 0.002).
conclusionType I lateral hinge fractures encroached either the anterior or posterior cortex of the proximal tibia, but not both. In addition, posterior tibial slope increased over time following surgery in knees with Type I lateral hinge fracture and posterior cortex breakage, suggesting that caution should be exercised when deciding the starting time for weight bearing in such patients. LEVEL OF EVIDENCE: Case series, Level IV.
