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
Objectives: This study evaluated the effectiveness of acids on calcium silicate cement surface hardness, perforation, and their impact on root dentine microstructure. Materials and methods: Root dentine discs were exposed to hydrochloric, acetic, and citric acids. Fourier transform infrared spectroscopy (FTIR) assessed dentine microstructure after exposure to these acids. Sixty discs of Biodentine and NeoPUTTY ( Results: FTIR revealed that hydrochloric acid caused severe demineralization of dentine microstructure, whereas 2% acetic and 5% citric acids had no significant effect on dentine microstructure. Both acids (acetic and citric) significantly reduced VHN compared to controls ( Conclusions: Acetic and citric acids significantly reduced microhardness and facilitated mechanical perforation of calcium silicate cements, with citric acid exerting greater effect.
