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
Background: Maxillary Transverse Deficiency (MTD) is a condition that affects the balance and functionality of the stomatognathic system. The aim was to evaluate maxillary bone thickness at the level of the midpalatal suture (MPS) using Cone Beam Computed Tomography (CBCT) in skeletal Class II individuals with maxillary transverse deficiency (MTD) and those with normal transverse maxillary width. Material and Methods: A total of 111 complete cranial scans from patients aged 18 years or older with skeletal Class II malocclusion were analyzed. This classification was confirmed by measuring the ANB angle and convexity at point A. The patients were divided into two groups based on their transversal conditions: the normal transversal maxillary width group (n=46) and the atresia group (n=65). The classification followed the University of Pennsylvania (U-Penn) method using Planmeca Romexis® software. Additionally, the vertical thickness of the maxillary bone was measured at three specific points (anterior, middle, and posterior) using sagittal views. Four maxillary thickness measurements were evaluated: nasopalatine canal thickness (NCT), middle maxillary thickness (MMT), anterior maxillary thickness (AMT), and posterior maxillary thickness (PMT). Statistical analyses included Student's t-test, linear multiple regression, and Pearson correlations. Results: The maxillary atresia index showed a mean difference of 5.82 mm between the two groups (p<0.001), favoring the adequate-width group. The four maxillary thickness measurements evaluated did not show significant differences between the groups (p>0.05). Furthermore, a low but significant correlation was found between maxillary atresia and bone thickness in the nasopalatine canal and the posterior maxilla, specifically for NCT (R=0.202, p=0.033) and PMT (R=0.205, p=0.031). Among all the analyzed variables using multiple linear regression, only the posterior maxillary thickness (PMT) was found to influence the occurrence of atresia significantly. It was determined that for every millimeter increase in this thickness, the maxillary atresia index increased by 0.78 points (p=0.005). Conclusions: The transverse dimensions of the maxilla in individuals with skeletal Class II affect its vertical dimensions; regardless of the initial transverse condition, a narrower maxilla correlates with greater posterior palatal thickness.
