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

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

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)**
  1. * p < 0.1; ** p < 0.05
  2. 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.
