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
Objectives: This study aimed to determine the prevalence and radiographic characteristics of supernumerary teeth (ST) in a Saudi population using cone beam computed tomography (CBCT). The research also explored the clinical and orthodontic implications of ST on tooth eruption and treatment planning. Methodology: A retrospective cross-sectional study was conducted at the Department of Diagnostic Sciences, College of Dentistry, Qassim University. A total of 992 CBCT scans obtained between January 2020 to January 2024 were reviewed. Demographic and radiographic variables-such as morphology, orientation, eruption status and relationship with adjacent teeth-were recorded in Microsoft Excel. Two calibrated oral radiologists independently evaluated the scans. Statistical analysis, including descriptive statistics and chi-square tests, was performed using SPSS version 27.0. Results: Supernumerary teeth were detected in 28 patients, indicating an overall prevalence of 2.82%. The prevalence among males (5.61%) was significantly higher than in females (1.10%). Most individuals presented with a single ST (67.86%). The common morphologies were conical (46.15%) and supplemental (38.46%). A majority were impacted (76.92%) and exhibited an inverted orientation (33.33%). In 20.51% of cases, ST obstructed the eruption of adjacent permanent teeth. Conclusions: Supernumerary teeth in this population showed a strong male predilection and were predominantly conical, impacted and inverted. CBCT was instrumental in their detailed assessment.
