A table demonstrating the confidence level in identifying the type of the image quality errors and specifying an appropriate error-correction strategy for both groups

			Pre-test confidence level	Post-test confidence level	Change in confidence level
Confidence level in identifying the type of the image quality errors	Group	Valid N	Median (1RQ)	Median (IRQ)	Median (IRQ)
	Control	16	90 (80-100)	90 (80-100)	0 (0-0)
	Experimental	19	90 (80-100)	85 (80-85)	0 (−5-0)
Confidence level in specifying the error-correction strategy	Control	16	80 (72-95)	80 (80-98)	0 (0-0)
	Experimental	19	85 (75-90)	80 (80-85)	0 (−5-5)
