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
objectivesTo elucidate the effect of microstructure on the strength and translucency of dental zirconia fabricated using additive (AM) and subtractive manufacturing (SM) technologies.
methodsTwelve 3Y-TZP discs were fabricated using AM with two print orientations (0°: group AM0; 90°: group AM90; n = 6), and six via CAD/CAM machining (group SM). Density, composition, roughness, translucency parameter (TP), and biaxial flexural strength (σ) were evaluated. Fractographic analysis was conducted and defect size estimated. Based on the preliminary σ results (n = 6), the optimal print orientation was identified. Nine additional specimens were prepared for each of the AM90 and SM groups for Weibull σ analysis (n = 15). Differences in Weibull modulus were assessed via non-overlapping 95 % confidence intervals. An one-way ANOVA followed by Tukey's post-hoc test and an independent samples t-test were used (α = 0.05).
resultsThe relative density was consistent across all groups (>99 %). The tetragonal and cubic phases were comparable among groups, with proportions exceeding 82 wt% and 17 wt%, respectively. Group SM exhibited significantly higher roughness (1.18 µm) than AM0 (0.71 µm) and AM90 (0.51 µm). Group SM exhibited the highest TP values, while groups AM0 and AM90 had statistically similar TP values. AM0 showed the lowest σ value (411.60 ± 73.99 MPa) and larger defects. Groups AM90 and SM (n = 15) possessed comparable σ values (969.85 ± 123.13 MPa and 989.72 ± 107.78 MPa, respectively) (p = 0.6417) and Weibull moduli (9.17 and 10.62, respectively). SIGNIFICANCE: SM zirconia showed higher translucency and roughness, while defects reduced translucency in AM zirconia. Flexural strength was lower for AM0 due to larger defects, whereas AM90 matched SM strength.
