Evaluating the precision and reproducibility of cephalometric landmarks in locally reconstructed lateral cephalometric radiographs from cone beam computed tomography (CBCT).
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThe commonly used lateral cephalometric radiographs, including traditional lateral cephalometric radiographs and CBCT-synthesized lateral cephalometric radiographs, have the problem of overlapping anatomical structures, which interferes with the identification of landmarks. Therefore, we proposed a new method called CBCT-based locally reconstructed lateral cephalometric radiographs and evaluated its precision and reproducibility. MATERIALS AND
methodsCBCT and lateral cephalometric radiographs were obtained from five orthodontic patients. Twenty-six cephalometric landmarks were identified using three methods by ten orthodontists. The landmarks on each image were recorded as (X, Y), and the absolute values of the differences between each measurement and the average values of the X and Y coordinates were calculated (ΔX and ΔY). Additionally, the distance between each located point and the centroid was calculated (ΔD). The differences in ΔX, ΔY, and ΔD among the groups were compared through analysis of variance (ANOVA). Bonferroni post hoc correction was used for pairwise comparisons. p < 0.05 was considered statistically significant.
resultsThe reproducibility of 14 landmarks in the CBCT-based locally reconstructed lateral cephalometric radiographs was better than that of the other methods in at least one direction (p < 0.05). Among these landmarks, the precision of the CBCT local reconstruction group was greater in all directions for five landmarks than that of the other two groups (p < 0.05).
conclusionThe CBCT locally reconstructed lateral cephalometric radiographs proposed in this study enhanced the precision and reproducibility of cephalometric landmark identification.
