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
purposeThe aim of the study was to assess the impact of various surface treatments, including an Er: YAG laser with different power outputs, on the shear bond strength (SBS) of different resin matrix CAD/CAM ceramic materials to resin luting cement. MATERIALS AND
methodsSpecimens from Lava Ultimate (LU) and Vita Enamic (VE) were categorized based on the surface treatment: no treatment, sandblasting (Sb), 10% hydrofluoric acid (Ac) etching, sandblasting followed by acid etching (Sb + Ac), and Er: YAG laser irradiation at 2 W and 3 W (L1, L2). Scanning electron microscopy (SEM) evaluation and roughness measurement of the samples were performed. Silane was applied to half of the specimens, resin cement was bonded and SBS testing was performed.
resultsThe SBS did not differ depending on the material (P = 0.081), but varied according to the surface treatment (P < 0.001). The highest mean SBS value was observed in the Sb + Ac (15.20) group. The highest roughness median was in Sb of VE, which was similar to Sb + Ac and Sb of all materials.
conclusionApplying Sb and Ac together was more effective than applying them separately. Although 2 W and 3 W Er-YAG applications were ineffective for treating VE's surface, 2 W Er-YAG applications can be suggested for LU. CLINICAL RELEVANCE: The combined application of Sb and Ac is more effective than their individual applications and laser irradiation in terms of resin matrix CAD/CAM ceramics retention.
