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
objectivesThis study aimed to investigate the correlation between the dental cervical morphology (DCM) of maxillary anterior teeth and facial parameters, with the goal of validating the predictive efficacy of these facial parameters for DCM of the maxillary anterior teeth in a Chinese population. MATERIALS AND
methodsThis cross-sectional study was conducted at Stomatology Hospital of Fujian Medical University. Facial parameters of participants were obtained using a 3D facial scanner and subsequently imported into reverse engineering software for measurement. Cone beam computed tomography (CBCT) data were imported into imaging software, where specific landmarks were annotated. The distance between these landmarks at the cemento-enamel junction (CEJ) level was then quantified and defined as dental cervical morphology (DCM). Pearson correlation analysis was employed to identify relationships between facial and DCM measurements. Linear regression was performed on significantly correlated variables, while t-tests evaluated the difference of real value and predicted value (α = 0.05).
resultsA total of 147 volunteers participated in this study. Significant correlations for DCM were observed with interlateral canthus width (LCW) in males (P < 0.05) and with intermedial canthus width (MCW) in females (P < 0.05). Regression equations based on facial parameters showed no significant differences between predicted and actual values for DCM (P > 0.05), with LCW used for males and MCW for females (P > 0.05).
conclusionsDCM of the maxillary anterior teeth was found to be associated with facial width, with LCW serving as a potential predictor for males and MCW for females. These findings suggested that facial morphology could be a valuable predictor for DCM. CLINICAL RELEVANCE: Facial parameters offer a reliable basis for the precise design of customized abutments, enhancing the accuracy and efficiency of clinical prosthodontic treatments, particularly in implantology and aesthetic restoration.
