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
backgroundThis study aimed to develop ion-releasing and antibacterial resin-based dental sealants comprising 3 to 6 wt% monocalcium phosphate monohydrate (MCPM, M), 3 to 6 wt% bioactive glass (BAG, B), and 3 to 6 wt% polylysine (PLS, P). The physical properties, mechanical performance, cytotoxicity, and inhibition of S. mutans biofilm by these materials were subsequently evaluated.
methodsFive experimental dental sealants were formulated as follows: F1 (M6B6P6), F2 (M6B6P3), F3 (M3B3P6), F4 (M3B3P3), and F5 (M0B0P0, serving as the control). ClinproXT (CP, 3 M, Saint Paul, MN, USA) was used for commercial comparison. The degree of monomer conversion (DC) was determined using attenuated total reflectance-Fourier transform infrared spectroscopy (n = 5). The biaxial flexural strength (n = 6) and Vickers surface microhardness (n = 5) of the materials were evaluated after a 24-hour immersion in water. The element release over 4 weeks was measured using inductively coupled plasma-optical emission spectrometry (ICP-OES) (n = 3). The cell viability of mouse fibrosarcoma cells exposed to the extract was assessed via an MTT assay (n = 3). Additionally, the inhibition of S. mutans biofilm was tested (n = 3). Statistical analysis was conducted using one-way ANOVA and the Tukey HSD test.
resultsThe lowest DC among experimental sealants was obtained from F1 (66 ± 4%), which was significantly higher than CP (54 ± 2%, p < 0.001). The lowest biaxial flexural strength was obtained from F3 (131 ± 47 MPa). This was comparable to that of CP (140 ± 58 MPa, p = 0.992). The lowest surface microhardness among experimental materials was detected with F2 (19 ± 2 Vickers hardness number), which was higher than that of CP (12 ± 1 Vickers hardness number, p = 0.003). Furthermore, high cell viability of > 90% after exposure to extracts from the experimental materials was detected, which was similar to that observed with CP. Additionally, the experimental materials exhibited higher Ca and P release compared to CP and showed a potential trend for reducing S. mutans biofilm formation. Increasing additive concentrations exhibited minimal effects on material properties, except for enhanced elemental release and a slight reduction in BFM with higher PLS content.
conclusionThe experimental sealants provided sufficient physical and mechanical strength and maintained cell viability and bacterial inhibition with higher elemental release than the commercial product.
