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
Over-instrumentation can result in excessive and inappropriate dentin removal, especially in root canals with complex internal anatomy. Therefore, it is of interest to evaluate changes in root canal volume of permanent mandibular premolars after preparation with OneShape, Standard Mani-Silk and Blueflex Acer file using CBCT and 3D reconstruction. Hence, 45 teeth were divided into three groups, instrumented with the respective file systems and pre- and post-instrumentation canal volumes were measured using Blue Sky Plan and MeshMixer software. The results showed that all file systems significantly increased canal volume (p<0.001), with Blueflex Acer file producing the highest volume change, followed by OneShape and Standard Mani-Silk the least. Standard Mani-Silk showed the best preservation of canal anatomy, suggesting its suitability for conservative endodontic preparation.
