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
backgroundThe anatomy of the proximal tibia presents treatment challenges, and there is currently no widely accepted surgical fixation method for fractures in this region. The aim of this study is to evaluate the efficacy, benefits, and differences between intramedullary nailing (IMN) with a 4-hole Limited Contact Dynamic Compression Plate (LC-DCP) combination and IMN with an 8-hole LC-DCP combination in unstable fractures of the proximal metaphyseal region of the tibia.
methodsAn oblique fracture was created in the metaphyseal region, forming a 30-degree angle in the sagittal plane in three tibial models. The fracture was designed to be 5 cm distal to the knee joint anteriorly and 8 cm distal to the knee joint posteriorly. One model was fixed with intramedullary nailing alone, while the others received additional fixation with either a 4-hole or an 8-hole plate in addition to the nail. Finite element analysis was performed using 3D computed tomography images of the models. Deformation, displacement, von Mises stress, and maximum principal strain values resulting from axial, lateral, coronal, and rotational forces applied to the models were analyzed.
resultsThe model fixed with intramedullary nailing alone demonstrated greater maximum stress, maximum deformation, and displacement under all applied forces. In the model with nail and 8-hole plate, unlike the other models, the highest amount of stress in the nail was concentrated on the distal locking screw under axial force. We observed that the maximum principal strain in the tibia was higher in the models with combined nail and plate fixation than in the model with intramedullary nailing alone.
conclusionThe results of this study indicate that the combination treatment with an 8-hole DCP plate is biomechanically superior for treating unstable proximal tibial fractures with nails. Although the nail-plate combination requires an additional surgical incision and extra implants, it provides advantages in terms of stability and the sustainability of fracture reduction in unstable fractures.
