Personal endotoxin exposure in a panel study of school children with asthma

Table 4 Associations of personal log endotoxin with indoor, outdoor and ambient log endotoxin¹

Predictor Variable	N	All Subjects coefficient (95% CI)	N	Riverside coefficient (95% CI)	N	Whittier coefficient (95% CI)
14 Subjects in Indoor-outdoor Monitored Homes,
Log Indoor Endotoxin	116	0.09 (-0.51, 0.68)	23	0.31 (-1.09, 1.72)	92	-0.03 (-0.73, 0.67)
Log Outdoor Endotoxin	113	0.17 (-0.32, 0.66)	23	0.32 (-1.12, 1.75)	89	0.15 (-0.41, 0.70)
Log Ambient Endotoxin	109	0.39 (-0.20, 0.98)	23	1.09 (-0.76, 2.94)	72	0.39 (-0.26, 1.04)
All 45 Subjects
Log Ambient Endotoxin	339	0.37 (0.04, 0.71)**	82	0.66 (-0.07, 1.38)*	256	0.39 (0.02, 0.76)**

* p < 0.1; ** p < 0.05
¹Results of linear mixed effects models show the change in log personal endotoxin for a one log-unit change in the predictor variable, adjusted for personal temperature, personal relative humidity, and region (all-subject model only). The sample sizes (N) represent person-days of observation with non-missing personal temperature and relative humidity.
