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
Introduction: The objectives of this study were to design a 3D-printed custom guide for segmental mandibulectomy in the dog and evaluate the impact of different materials (metal versus polymer) on the performances of the guided procedure in cadaveric dogs. Methods: Twenty canine cadaveric heads were randomized in two study groups and received bilateral segmental mandibulectomies performed with a metal or polymer surgical guide. Pre-operative computed tomography (CT) images of the skull were used to design custom 3D-printed surgical guides and were repeated after placement and osteotomy. Mean absolute linear deviation between planned and performed cuts, procedure duration, and qualitative assessment were compared. Results: Polymer guides were associated with easier ( Discussion: Overall, the study did not demonstrate any difference in accuracy between materials but highlighted differences in performance specific to each material. Thus, surgical guide manufacturing and material choice could be tailored to specific clinical applications, whether strength/durability or flexibility/conformability is favored.
