1 · What the graph read from it

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.

2 · The registry

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

To evaluate the repair bond strength of a nanohybrid resin composite to aged machinable hybrid ceramic after using three surface pretreatments. Specimens of the hybrid ceramic blocks were grouped into four groups based on the ceramic surface pretreatment: no treatment control group, bur grinding group, HF etched group, and grit-blasting group. All the groups were tested for surface roughness by an optical profilometer. Test groups were subdivided into immediate and aged groups based on aging protocol. A nanohybrid resin composite was placed onto prepared resin/ceramic hybrid material surfaces for the micro shear bond strength test. Deboned specimens were inspected using a stereomicroscope and a scanning electron microscope to determine the failure mode. Data was analyzed using ANOVA and the Tukey's HSD test. One-way ANOVA test for surface roughness showed no significant difference among the differently pretreated surfaces. Two-way ANOVA after aging indicated significant differences of surface pretreatments and aging protocol on MSBSof the nanohybrid composite bonded to hybrid ceramic (p < 0.05). Surface pretreatments increased the bond strength of resin composite bonded to hybrid ceramic material. Aging had a detrimental effect on MSBSof nanohybrid resin composite to hybrid ceramic.
