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
Objective: This study aimed to investigate the influence of using different printers on surface roughness and hardness of different 3D printed dentures. Methods: Three denture base resins (ASIGA, NextDent, and FormLabs) were printed with one of two printers: ASIGA or NextDent. Surface roughness was measured with a non-contact profilometer, while a surface hardness tester was used to measure Vicker's hardness values. One-way and Two-way analysis of variance (ANOVA), and Results: FormLabs and NextDent specimens showed different hardness values when different printers were used ( Conclusions: The type and brand of the printer used can affect surface properties of printed dentures. When the same printer was used, surface roughness and hardness were significantly different among all resin materials. The choice of resin material and printer combination affects both surface roughness and microhardness. Clinical Significance: The choice of resin material and printer type may significantly impact the microhardness and surface roughness of 3D printed dentures. Careful material and printer selection is essential to ensure optimal clinical performance and longevity of prostheses.
