Table 1 Logistic regression analysis for the estimated probability of detection of MRSA with the following risk factors in the combined LTCFs subgroup and hospital subgroup

	Estimate	Standard error	z value	p value
(Intercept)	−3.257	0.189	−17.216	<0.001
Presence of nasogastric tube feeding	0.643	0.286	2.251	0.024
Presence of urinary catheter	1.318	0.259	5.094	<0.001
Chronic cerebral conditions	0.794	0.187	4.247	<0.001
Use of β-lactam/β-lactamase inhibitors within 3 months of MRSA screening	0.860	0.224	3.843	<0.001
Residence in LTCFs	1.218	0.205	5.945	<0.001

LTCFs, long term care facilities.
Hospital subgroup, defined as patients who were not referred from LTCFs; LTCFs subgroup, defined as LTCF residents who had not been hospitalized in the past 12 months.
Note. After adjusting the other confounding factors, the estimated odds for persons having MRSA in LTCFs is exp (1.218) ≈ 3.4 times than those not residing in LTCFs.
