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
backgroundThalassemia is a well-recognized hereditary blood disorder with systemic complications. However, its craniofacial and orthodontic alterations remain incompletely characterized. Current evidence is fragmented, and no comprehensive synthesis has been published hitherto.
aimsTo map and synthesize craniofacial and orthodontic alterations in individuals with thalassemia by identifying morphological patterns and associated clinical factors.
methodsThis scoping review included cross-sectional studies, cohort studies, and clinical trials retrieved from four databases and gray literature. Data were analyzed descriptively.
resultsTwenty-six studies (comprising 2,353 participants) published between 1964 and 2025 were included. Common findings included a Class II skeletal pattern, mandibular retrusion, maxillary protrusion, increased lower facial height, and thalassemic facies. Orthodontic anomalies included Class II malocclusion, anterior open bite, crowding, incisor protrusion, and transverse constriction of the arches (narrow skeletal arches). Greater severity was associated with chronic anemia, splenectomy, and delayed transfusion. Only one study evaluated functional appliance therapy, demonstrating improved mandibular advancement and facial esthetics.
conclusionThalassemia is associated with clinically relevant dentoskeletal alterations that affect function and esthetics. Early orthodontic evaluation and timely interceptive treatment should be prioritized, as they may attenuate deformity progression and improve craniofacial development, reducing the future need for complex orthognathic surgery.
