Table 3.

Adjusted associations between approach types and the outcomes, skin breaks and redirections, by cannulation site as referenced to the short axis.

Variable	Long Axis
Variable	Relative Risk	(95% CI)
Internal Jugular^§
Skin breaks	0.8	(0.5 – 1.4)
Redirections	0.4	(0.2 – 0.9)
Subclavian^‡
Skin breaks	1.7	(0.9 – 3.2)
Redirections	0.5	(0.3 – 0.7)

^§

Each IJ model was adjusted for year in training, estimated total number of internal jugular (IJ) lines placed, and perceived comfort with IJ US-guided central line placement.

^‡

Each subclavian (SC) model was adjusted for: year in training, estimated number of SC lines placed, estimated number of US-guided SC lines placed, and perceived comfort with US-guided SC central line placement.
