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
backgroundThe objective of this study was to evaluate the efficacy of the mandibular advancement protocol (MA) with clear aligners in the treatment of skeletal Class II malocclusion and to assess their effect on the mandibular trabecular structure using fractal dimension analysis (FD-A) on panoramic radiographs.
methodsThe study included panoramic and cephalometric radiographs of 20 patients (treatment group, mean age: 11.7 ± 0.8 years; 9 girls, 11 boys) with Class II malocclusion, treated with the mandibular advancement protocol (MA) using clear aligners. The radiographs were obtained before treatment (T0) and following the MA phase (T1). Additionally, panoramic radiographs of 20 control subjects who had undergone no orthodontic treatment (control group, mean age: 11.7 ± 0.9 years; 9 girls, 11 boys) were analyzed. The fractal dimension values of the mandibular trabecular structures in the condylar, gonial, and corpus regions were evaluated for both groups. Statistical analyses were performed using paired t-test and independent samples t-test for parametric data, and Wilcoxon test and Mann-Whitney U test for non-parametric data. Statistical significance was set at P < 0.05.
resultsThe treatment applied using MA with aligners resulted in significant decreases in SNA (P < 0.05), ANB (P < 0.05), 1-NA (P < 0.001), overjet (P < 0.001), and overbite (P < 0.01). Conversely, significant increases were observed in S-Go (P < 0.01) and 1-NB (P < 0.05) parameters. The FD-A changes between T0 and T1 indicated that the observed increases in the right and left condylar processes, the left gonial region, and the left mandibular corpus were not statistically significant in the treatment group (P > 0.05). The comparison of the FD-A results between the groups revealed no statistically significant differences (P > 0.05).
conclusionsThe FD-A results revealed no significant alterations in the trabeculation of the mandibular bone in the treatment group. These findings suggest that MA treatment with aligners primarily contributes to dental correction rather than inducing changes in the skeletal structure and trabeculation of the mandibular bone.
