Correlation between transverse and sagittal dimensions in early stage: a retrospective study between patients treated with clear aligners and untreated patients.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 interceptive treatment of Class II malocclusion using clear aligners is still debatable. This retrospective study analyzes the short-term occlusal and cephalometric effects in 40 growing patients with Class II malocclusion.
methodsThe sample was divided into 2 groups: Following the dentoalveolar expansion protocol, the first group was treated with clear aligners (GI). The second group was untreated (GN). Dental arches were scanned before and 1 year after the therapy. Similarly, linear measurements on digital casts and cephalometric ones on lateral X-rays were compared. Maxillary (Lmax), mandibular intermolar length (Lmand), and posterior transverse intermolar discrepancy (DIT) were evaluated. The distance between the mesiobuccal cusp of the upper first molar and the buccal groove of the first lower molar was considered at both sides (Cdx and Csx). The statistical descriptive analysis of T0 and T1 values was performed using a paired t-test, setting a p value < 0.05.
resultsA greater improvement in molar and skeletal Class II parameters in the GI group compared to the GN group was detected. Specifically, in GI, Lmax improved by 3.3 mm, Lmand by 1.1 mm, and DIT improved from - 2.1 mm to 0.1 mm, while Cdx and Csx decreased by 1.28 mm and 1.13 mm, respectively. In contrast, the GN group showed smaller improvements, with Lmax increasing by 1 mm, Lmand by 0.8 mm, DIT improving from - 2 mm to -1.8 mm, and both Cdx and Csx exhibiting slight increases of 0.04 mm and 0.09 mm, respectively. No statistically significant differences were observed regarding divergence or the correlation between skeletal and dental measurements.
conclusionsDentoalveolar expansion using Invisalign First appears effective and predictable with better outcomes than the control group. An improvement of skeletal Class II is detected in the treated group with dental improvements on maxillary arch.
