Transverse skeletal proportionality in the prognostic evaluation of facemask therapy for skeletal class III malocclusion: a retrospective cephalometric study.
Article in Progress in orthodontics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to identify prognostic skeletal factors associated with long-term stability following early orthopedic treatment in growing patients with skeletal Class III malocclusion by integrating lateral (LAT) and posteroanterior (PA) cephalometric analyses. MATERIALS AND
methodsForty-four growing patients with skeletal Class III malocclusion and maxillary retrusion treated with facemask therapy were retrospectively analyzed. Cephalometric records were obtained at pretreatment (T0), posttreatment (T1), and post-growth completion (T2). Patients were classified into favorable growth (FG) and unfavorable growth (UG) groups based on occlusal and skeletal outcomes at T2. Twenty lateral and fourteen posteroanterior cephalometric variables were assessed. Principal factor analysis with Varimax rotation was performed to derive latent skeletal components, which were subsequently evaluated using multiple linear regression to identify predictors of ANB at T2. A classification decision tree was constructed using T0 variables to classify long-term growth outcomes.
resultsFactor analysis yielded five principal variables (PV1-PV5), of which transverse maxillary structure (PV1), maxillomandibular transverse relationship (PV2), and vertical skeletal pattern (PV3) demonstrated significant associations with ANB at T2. A classification decision tree identified the transverse differential between mandibular and maxillary width (Mn. width - Mx. width) as the strongest initial discriminator of long-term prognosis, followed by AB-mandibular plane angle and Sum. The model achieved a classification accuracy of 93.2% in distinguishing favorable and unfavorable growth outcomes.
conclusionsTransverse skeletal proportionality plays a central role in determining the long-term stability of early orthopedic treatment in skeletal Class III malocclusion. Prognostic assessment may benefit from incorporating transverse, sagittal, and vertical skeletal dimensions including measurements from LAT and PA cephalograms, to improve individualized treatment planning and outcome prediction.
