1 · What the graph read from it

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.

2 · The registry

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

This systematic review and meta-analysis aimed to determine whether the morphology and linear dimensions of sella turcica differ by the different skeletal malocclusions. PubMed, Scopus, EMBASE, and Google Scholar were comprehensively searched for the relevant articles published until 21 May 2024 using combinations of the following terms: sella turcica, lateral cephalometric, skeletal malocclusion, and morphology. Observational studies that assessed sella turcica in different skeletal malocclusions in systemically healthy subjects were included. Data analysis was accomplished using R. Twenty-six studies were included and subjected to quantitative analysis. The length and diameter of sella turcica in Class III were higher compared to Class I [Mean Difference (MD) = 0.42, 95% CI: 0.18-0.67, p value < 0.001; and MD = 0.29, 95% CI: 0.05-0.53, p value = 0.0197, respectively], and compared to Class II (MD = 0.48. 95%CI: 0.23-0.73, p value ≤ 0.001, and MD = 0.4, 95%CI: 0.14-0.65, p value = 0.002, respectively). The depth of sella turcica in Class III was also higher than that of Class II (MD = 0.29, 95%CI: 0.03-0.56, p = 0.03. Furthermore, Class III showed the highest rates of bridge and notch shape of sella turcica compared to Class I (Risk Ratio (RR) = 1.42, 95%CI: 1.13-1.79, p value = 0.0026; and RR = 1.55, 95%CI: 1.11-2.17, p value = 0.011, respectively), and compared to Class II regarding the bridge shape (RR = 1.35, 95%CI: 1.07-1.71, p value = 0.012. The Class III malocclusion showed larger dimensions of sella turcica, and higher prevalence of bridging, notching, and double shape in sella turcica. The present findings do not provide direct diagnostic evidence for orthodontic clinical practice.
