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
Increased posterior tibial slope is a risk factor for anterior cruciate ligament reconstruction graft failure. In revision anterior cruciate ligament surgery, anterior closing-wedge high-tibial osteotomy (ACW-HTO) addresses increased tibial slope. ACW-HTO is technically challenging in accurately executing the desired bony cuts and degree of correction. Risks include posterior neurovascular injury, hinge fractures, coronal-plane alterations, and over/under alignment correction. We present a technique leveraging the accuracy of a computed tomography-based robotic knee arthroplasty system to plan and execute precise bone cuts for ACW-HTO. We carried out 3 ACW-HTO scenarios on a Sawbones model; supratubercle, infratubercle, and combined coronal plane osteotomy. After Sawbones computed tomography scanning the software was used to plan osteotomy trajectories. The tibial baseplate cut for knee arthroplasty was adapted to perform 2 angulated ACW-HTO bone cuts, rotated and positioned upon the desired posterior hinge point. Bone cuts were successfully executed using a robotically assisted saw, registering cuts to a high accuracy. Bony registration is permitted through the surgical approach for an ACW-HTO referencing only the anterior tibial cortex with 0.2-mm accuracy. This delivered excellent precision, matching planned corrections. Robotic haptic boundaries ensured safe limits posteriorly, hinge-point maintenance and coronal-plane control.
