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/
objectivesThe nasopalatine canal (NPC) shows considerable morphological variability and may be related to adjacent anatomical structures. The aim of this study was to investigate the relationship between NPC diameter and the morphometric and morphological characteristics of the infraorbital foramen (IOF) and greater palatine foramen (GPF), and to evaluate the changes associated with enlarged and pathological NPC conditions.
methodsCBCT images of 180 individuals were retrospectively analyzed. Participants were classified into four groups based on NPC diameter: normal, enlarged, suspected pathology, and histopathologically confirmed NPDC. NPC morphology was evaluated in coronal, axial, and sagittal planes. IOF and GPF measurements and morphological types were assessed bilaterally
resultsNo significant associations were found between NPC diameter and age, sex, or coronal morphology. In the axial plane, round (52.9%) and heart-shaped (42.9%) forms predominated in normal and enlarged groups, while oval morphology was more frequent in pathology (60.0%) and cyst groups (75.0%). In the sagittal plane, cylindrical (34.3%) and banana-shaped (38.6%) forms were dominant in normal and enlarged groups, whereas funnel-shaped morphology was more common in pathology (40.0%) and cyst groups (55.0%). Increasing NPC diameter was associated with higher IOF and GPF measurements and morphological changes.
conclusionsNPC enlargement is associated with morphological and dimensional variations in the IOF and GPF. These findings support the presence of measurable morphometric associations between NPC diameter and adjacent maxillofacial anatomical structures, particularly in enlarged and pathological NPC conditions.
