Summarizing table of calculated values for noise measurements in the study and control groups

Readers	SNR	Parameters
		Study group (100 kV; 30 ml) (mean value ± SD)	Control group (120 kV; 80 ml) (mean value ± SD)	p-value
First reader	Chest	11.6 ± 7.91	18.32 ± 7	0.0067
	Abdomen	10.8 ± 2.93	14.55 ± 4.21	0.0365
Second reader	Chest	12.6 ± 6.82	21.53 ± 6.42	0.0026
	Abdomen	11.2 ± 3.63	14.8 ± 5.31	0.0412

SD, standard deviation; SNR, signal-to-noise ratio.

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