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

objectiveTo investigate the effect of zirconia (Zr) surface treatment with different femtosecond laser (FS) wavelengths on the shear bond strength (SBS) of metal brackets to multilayer zirconia.

methodsA total of sixty-four zirconia disc-shaped samples were randomly divided into four equal groups (n = 16). Airborne- particle abrasion (APA) utilizing 50 μm alumina particles (Al

resultsThe APA group showed the greatest SBS value (17.23 ± 2.02 MPa), with no significant difference from the FS with 800 nm group (15.07 ± 3.42 MPa) or the FS with 870 nm group (13.01 ± 2.74 MPa). The FS 385 nm group showed significantly the lowest SBS value (8.07 ± 1.26 MPa) with P = 0.0001.

conclusionsThe femtosecond laser irradiation at 800 nm and 870 nm achieved comparable shear bond strength (SBS) to airborne-particle abrasion (APA), indicating its potential as an alternative zirconia conditioning method, although it did not surpass APA. Its effectiveness was highly dependent on the selected wavelength parameters.
