Summarizing table of mean radiation dose exposure in the thoracic and abdominal studies

Parameters	Study group (100 kV; 30 ml) (mean value ± SD)	Control group (120 kV; 80 ml) (mean value ± SD)	p-value
DLP chest	490 ± 100.60	1032 ± 89.21	<0.0005
DLP abdomen	334 ± 126.23	1078 ± 59.60	<0.0001
CTDIvol chest	13.85 ± 6.02	27.78 ± 3.13	<0.0005
CTDIvol abdomen	5.83 ± 1.9	22.51 ± 1.94	<0.0001

CTDIvol, CT dose index volume; DLP, dose–length product; SD, standard deviation.

p < 0.05 indicates the difference between study and control group.
