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
INTRODUCTION AND
aimsAdditive manufacturing technology has the potential to produce accurate restorations in the field of prosthodontics. This in vitro study aimed to investigate the dimensional accuracy and marginal and internal fit of monolithic zirconia crowns fabricated with advanced customized jetting (ACJ) technology, a material jetting method, based on clinical laboratory data.
methodsThe three-dimensional (3D) printed tooth preparation casts for ceramic complete crowns of the maxillary central incisor and mandibular first molar (n = 10 for each tth, a total of 20) were collected from a dental laboratory. All casts were digitally scanned, and 40 crowns were fabricated by using ACJ and subtractive manufacturing (SM) methods (n = 10 per manufacturing method for incisors and molars). The dimensional accuracy was determined by superimposing the scanned crown data with the corresponding design data. Marginal and internal fit were evaluated with a dual scanning method.
resultsSignificant differences were found in the dimensional accuracy and adaptation among the ACJ and SM groups (P < .05). ACJ crowns demonstrated significantly higher accuracy and lower root mean square (RMS) values in the overall, external, marginal, and intaglio regions compared with SM (P < .001). Regarding adaptation, ACJ crowns exhibited smaller marginal gaps, occlusal gaps in molars, and axial gaps in incisors than SM crowns (P < .05).
conclusionMonolithic zirconia crowns fabricated by using ACJ demonstrated superior dimensional accuracy and adaptation compared with SM based on clinical laboratory data. CLINICAL RELEVANCE: Advanced customized jetting technology enables the fabrication of monolithic zirconia crowns with favorable dimensional accuracy and marginal and internal fit. This capability demonstrates its significant potential for complete crown production based on clinical laboratory data.
