Altered level of consciousness	23.462	[3.129, 175.901]	0.002
At least one CAM feature	2.822	[1.327, 6.001]	0.007
At least three CAM features	7.219	[0.886, 58.806]	0.065

Note. CAM = Confusion Assessment Method (Inouye et al., 1990). Items in bold indicate statistical significance.

The odds ratio determined the likelihood of nurses documenting the attribute in the group with delirium superimposed on dementia versus the group without dementia.

Not enough data were provided to run the regression analysis on this attribute.
