Multiple linear regression model with radiation dose acting as the dependable variable.

	Radiation Dose of CCTA
Linear Regression	β	p-Value	95% CI
Gender	0.08	0.25	(−40.6, 70.7)
Age	0.20	0.005	(1.0, 5.6)
BMI	0.39	0.001	(6.8, 19.3)
Tube Voltage	0.47	<0.001	(3.8, 9.0)
Scan Range	0.18	0.014	(0.8, 6.8)

The overall p-value of the model was significant (p = 0.01). Abbreviations: CI, Confidence interval; BMI, body mass index. Data in parentheses represent the 95% confidence interval range.
