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
backgroundNasal septum deviation (NSD) plays a vital role in paranasal sinus development, influencing sinonasal structures and maxillary sinus volume (MSV). This study aims to identify the NSD types and ascertain their impact on sinonasal variants, MSV, and morphometry of the infundibulum using three-dimensional (3D) computed tomography (CT) scans.
methodsCT images of 300 patients (150 females and 150 males), aged between 18 and 70 years, were retrospectively analyzed. The prevalences of NSD types, NS pneumatization (NSP), middle concha bullosa (MCB), paradoxical middle turbinate (PMT), MS mucosal thickening (MSMT), accessory maxillary ostium (AMO), uncinate process (UP) variants, and inferior turbinate hypertrophy (ITH) were evaluated. Also, MSV, MO width (MOW), infundibulum length (IL) and angle (IA) were measured. Statistical analyses of data was done taking into account gender, laterality, and age.
resultsThe greater the degree of NSD, the greater the likelihood of MCB, PMT and ITH occurring on the opposite side. Conversely, AMO, hypoplastic MS, MSMT, and hook-shaped UP were more prevalent on the same side of the deviation. The strongest associations with ipsilateral hyperplastic MS and being a young male were exhibited by PMT and MCB. Moderate and severe NSD, AMO, hook-shaped UP, hypoplastic MS and MSMT were more prevalent in older subjects, while younger subjects had more NSP, extensive MCB, PMT with a significant difference. The mean MSV, MOW and IL were found to be lower in MS on the same side of NSD, while the largest IA was observed in MS with severe NSD, as well as larger IA on the ipsilateral side of deviation, with a significant difference. However, we found that, as the degree of NSDA increased, the mean IL decreased and the mean MOW increased. The mean MOW and IL values indicated a positive correlation with ageing, whereas the MSV and IA values decreased with increasing age.
conclusionsDespite their significance, our understanding of how sinonasal structures, MSV, and infundibulum morphometry vary and covary with NSD remains limited, a crucial aspect in the planning of dental implantology and endoscopic sinus surgery.
