Sinus membrane thickness and its correlation with anatomical parameters using cone beam computed tomography: a cross-sectional study.
Article in Scientific reports, 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
This study evaluated and correlated sinus membrane thickness with anatomical parameters in periodontally healthy individuals (Group I) and Stage III periodontitis patients (Group II) using CBCT. Eighty systemically healthy patients (19–65 years) were equally divided into two groups. Sinus membrane thickness was measured at three standardized points (A, B, C), along with sinus width and sinus angle. Group II demonstrated significantly greater membrane thickness at all points (e.g., AR: 3.58 ± 1.28 mm vs. 2.17 ± 1.70 mm; BR: 3.50 ± 0.88 mm vs. 2.26 ± 0.84 mm; CR: 3.45 ± 0.79 mm vs. 1.85 ± 1.16 mm; all p = 0.0001). Sinus angles at AR, AL, and CL were significantly smaller in Group II (e.g., AR: 75.48 ± 8.59° vs. 82.15 ± 4.38°, p = 0.0001). The point of maximum membrane thickness was also higher in Group II (right side: 4.02 ± 1.44 mm vs. 3.08 ± 1.88 mm, p = 0.016). Sinus width showed no significant differences between groups (right side p = 0.857; left side p = 0.920). Across both groups, males exhibited greater mucosal thickness than females. Overall, periodontal disease was associated with increased sinus mucosal thickening and alterations in sinus morphology.
