Table 4 Logistic regression analysis for the estimated probability of detection of MRSA with the following risk factors in the LTCFs subgroup

	Estimate	Standard error	z value	p value
(Intercept)	−0.422	0.578	−0.729	0.46588
Presence of urinary catheter	2.125	0.660	3.219	0.00129
Chronic cerebral conditions	0.742	0.256	2.899	0.00374
Area (square feet) per person ^a	−0.014	0.006	−2.648	0.0081

LTCFs, long term care facilities; LTCFs subgroup, defined as LTCF residents who had not been hospitalized in the past 12 months; ^a area per person is defined as total area of the LTCFs over the number of resident occupying at the time of study.
Note. The odds of a patient having MRSA decreased by exp (−0.14) ≈ 0.90 times with each 10 square feet increase in area (square feet) per person when the other risk factors of presence of urinary catheter and chronic cerebral conditions were held constant.
