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
purposeTo compare the biomechanical performance of a configuration of two lateral pins and one condylo-trochlear sulcus pin (L2C1) with that of established pinning techniques using finite element analysis.
methodsA simplified transverse distal humeral fracture model was created from quantitative computed tomography data of both humeri of a single healthy adult volunteer. Five lateral-entry and crossed pin configurations, including L2C1, were analyzed under flexion, extension, varus, valgus, internal rotation, and external rotation.
resultsL2C1 showed the greatest fixation stability under extension, varus, and valgus loading. Under rotational loading, crossed pinning demonstrated the greatest fixation stability, whereas L2C1 showed stability comparable to lateral three-pin fixation.
conclusionsIn this adult humerus-based finite element model, the L2C1 configuration showed favourable fixation stability under extension, varus, and valgus loading compared with conventional lateral-entry pinning. Further anatomical, experimental, and clinical validation is required before extrapolation to paediatric supracondylar humeral fractures and clinical use.
