New population-specific cephalic index standards for Malaysian subadults: prevalence, growth patterns, and clinical implications from a CT imaging study.

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
objectivePopulation-specific Cephalic Index (CI) classifications are lacking for Malaysian subadults. This study aimed to develop a new CI classification and determine the prevalence of deformational brachycephaly using Computed Tomography (CT) images.
methodsA total of 520 CT images from subadults aged 0- to 20-years were included in the study. Two cranial measurements were obtained: the maximum Cephalic Length (CL) and the maximum Cephalic Width (CW), derived from axial CT images. The CI was subsequently calculated using the formula: CW/CL × 100. In addition, a simple linear regression analysis was performed to evaluate the relationship between CI and age.
resultsThe modified CI ranges for the Malaysian subadult population were defined as follows: dolichocephalic ≤ 78.8, mesocephalic 78.9-89.0, brachycephalic 89.1-94.0, and hyperbrachycephalic ≥ 94.1. The predictive equation derived was y = 87.08-0.47x +0.01×
conclusionThis new, population-specific classification provides an essential reference tool for clinicians and researchers to accurately detect, manage, and treat cranial deformities in Malaysian subadults, with significant applications in pediatrics, anthropology, and forensic medicine.
