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
Context: Root canal shaping is critical in endodontic treatment, aiming to maintain canal anatomy while effectively removing infected tissue. Aim: The aim of this study was to compare the volumetric changes and uninstrumented areas in root canals prepared with ProTaper Ultimate (PTU) and ProTaper Next (PTN) file systems using micro-computed tomography (CT). Settings and Design: This was an Materials and Methods: Pre- and postinstrumentation micro-CT scans were performed at 13 Statistical Analysis Used: Unpaired Results: PTU demonstrated significantly lower canal volume gain (13.20% ±1.95% vs. 21.12% ±2.7%) and tooth volume loss (0.588% ±0.18% vs. 0.95% ±0.12%) compared to PTN. Conclusions: The PTU system demonstrated superior preservation of tooth structure with less canal enlargement while maintaining effective instrumentation of canal surfaces compared to PTN, likely due to its enhanced flexibility, smaller core diameter, and improved metallurgy.
