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
Background: Coronal microleakage compromises the longevity of root-filled teeth. Intra-orifice barriers are used to reduce coronal ingress, but comparative performance among bioceramics remains uncertain. This study aimed to evaluate the coronal microleakage of two bioceramic materials, NeoPutty and mineral trioxide aggregate (MTA) Plus, used as intraorifice barriers in extracted human single-rooted premolars. Materials and Methods: This randomized controlled Results: The mean dye penetration with standard deviation (SD) was 5.49 (1.72) mm for NeoPutty and 5.21 (1.11) mm for MTA Plus; the difference was not statistically significant (NeoPutty - MTA Plus = 0.275 mm; 95% confidence interval [CI], -0.651-1.201; Conclusion: Both NeoPutty and MTA Plus showed similar coronal sealing effectiveness as intraorifice barriers in premolars. These results support the use of either material to enhance the coronal seal. Further studies incorporating aging protocols and alternative leakage models are recommended.
