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: Morphological studies of the bony palate remain limited. This study aimed to investigate the three-dimensional relationship between the bony palate and the hard palatal mucosa, as well as palatal dimensional differences according to anteroposterior jaw relationships, using CT data. Methods: CT data from 116 female patients (95 young adults; 15-29 years, 21 middle-aged adults; 30-56 years) who required orthodontic treatment combined with orthognathic surgery were analyzed morphometrically using medical image-processing software. The anteroposterior relationship between the maxilla and mandible was determined using lateral cephalograms, and participants were divided into three groups: Class I (normal maxillomandibular relationship), Class II (maxilla positioned anterior to the mandible), and Class III (mandible positioned anterior to the maxilla). Intergroup palatal dimensional differences were analyzed using non-parametric tests (Wilcoxon test and Steel-Dwass test). Results: Palatal mucosal thickness in the first molar region (PMT) showed substantial inter-individual variation, with no significant age-related differences. Palatal width was narrower, whereas palatal length was greater in Class II than in Class III. Palatal depth was greater in Class II than that in Classes I and III at the first premolar (P1), but no intergroup difference was observed at the first molar (M1). Conclusion: PMT showed no age-related differences and may serve as a representative indicator of palatal mucosal structure. In Class II, the bony palate was narrower and deeper in the P1 region, whereas the palatal depth in the M1 region did not differ significantly from that in Classes I and III.
