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
Objective: The purpose of this study was to investigate the effects of intraradicular moisture conditions and canal morphologies on the filling quality of iRoot SP with single-cone technique in root canals. Materials and methods: Eighty-four human single-rooted premolars root canals were pair-matched with similar root canal volumes, aspect ratio (AR) curve shapes, and 3D models after micro-computed tomography (micro-CT) scanning to establish baseline consistency. Root canals were then prepared and assigned to 4 experimental groups with respect to the moisture condition tested: (1) Paper point normal drying (2) ROKEO drying (3) Paper point preliminary drying (4) Wet, followed by filling with iRoot SP single-cone technique. The effects of moisture conditions on root filling quality were studied by calculating the volume percentage of voids through micro-CT scanning and the number and score of voids under dental operating microscope (DOM) observation of the cross-sectional slices. Then classified different cross-sectional anatomical morphologies of the root canals based on the AR value and their impact on the volume percentage of voids after root canal filling were evaluated. Results: Unified the sample baseline through micro-CT pair-matching, both micro-CT and DOM provided complementary information showed that paper point normal drying and ROEKO drying displayed the lowest voids in terms of volume, number and score Conclusion: The intraradicular moisture conditions and cross-sectional anatomical morphology had significant effect on the filling quality of iRoot SP with single-cone technique.
