SURG-TLX average values for the intrinsic components of cognitive load

	Mean of SURG-TLX Score for ENB	Mean of SURG-TLX Score for RB	P Value
Mental demands	3.6	3.4	0.03
Physical demands	2.0	1.6	0.55
Temporal demands	2.5	2.7	0.64
Task complexity	4.1	3.7	0.03

Definition of abbreviations: ENB = electromagnetic navigational bronchoscopy; RB = robotic-assisted bronchoscopy; SURG-TLX = Surgery Task Load Index.

Average values for SURG-TLX for both ENB and RB. P values to detect a difference between ENB and RB are shown. Note that extrinsic SURG-TLX categories (situational stress and distractions) were removed because they were not the focus of the article.
