Association between nasal cavity anatomical variations and palatal dimensions in pediatric patients: a CBCT study.
Article in BMC oral health, 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 retrospective cross-sectional study aimed to evaluate the associations of nasal septum deviation (NSD), concha bullosa (CB), and inferior turbinate hypertrophy (ITH) with palatal dimensions using cone-beam computed tomography (CBCT).
methodsCBCT images of patients younger than 18 years obtained between January 2021 and May 2025 were retrospectively evaluated. A total of 108 eligible subjects were included and categorized into four groups based on the presence of NSD and CB. Maxillary palatal arch angle (MPAA), palatal interalveolar length (PIL), and palatal depth (PAD) were measured. Group comparisons were performed using age-adjusted ANCOVA, and associations between palatal measurements, deviated septal curve angle (DSCA), and age were analyzed using correlation and regression analyses.
resultsUnadjusted analyses revealed significant age differences among the groups. After age adjustment, no significant differences were observed in MPAA, PIL, or PAD (p > 0.05). A weak positive correlation was found between DSCA and MPAA (r = 0.219; p = 0.023), whereas no significant correlations were detected for PIL or PAD. Regression analysis showed that age was the only significant predictor of palatal measurements.
conclusionAge was the only significant predictor of palatal measurements in this pediatric sample. Within the CBCT-based anatomical variables evaluated, NSD, CB, and ITH were not independently associated with palatal dimensions after adjustment for age. These findings should not be generalized to functional nasal obstruction or respiratory patterns, which were not assessed in this study.
