Assessment of the association between C2 vertebral morphology and facial asymmetry using CBCT and panoramic radiography.

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
purposeTo investigate the relationship between the morphology of the Axis (C2 vertebra) and facial asymmetry using cone-beam computed tomography (CBCT) and panoramic radiographs. MATERIALS AND
methodsA retrospective evaluation was performed on CBCT and panoramic radiographs of 50 patients (aged 18-45 years) selected from university archives. Axis vertebral morphology was assessed on CBCT using angular and perpendicular measurements of the dens and transverse processes. Facial asymmetry was evaluated on panoramic radiographs by measuring bilateral distances and angles from the condylion to the midsagittal plane. Pearson's correlation and Chi-square tests were used to analyze associations. Sample size was calculated based on a priori power analysis.
resultsModerate but statistically significant correlations were identified between specific vertebral and facial asymmetry parameters. A negative correlation was observed between the right Axis angle and the right Co-ANSMe perpendicular distance (r = - 0.31, p = 0.026), while the left Axis perpendicular distance showed a positive correlation with both right (r = 0.36, p = 0.009) and left (r = 0.33, p = 0.018) Co-ANSMe perpendicular distances. Additionally, combined measurements of Axis and Co-ANSMe distances demonstrated a moderate positive correlation (r = 0.31, p = 0.028). No other statistically significant correlations were found.
conclusionsMorphological differences in the Axis vertebra appear moderately associated with transverse facial asymmetry. These findings may offer additional reference points for radiographic assessment. Further studies with larger samples are recommended to confirm these observations.
