Agreement, Sensitivity, and Specificity of Self-Reported Exposure to Vapors, Gas, Dust or Fumes against Job Exposure Matrix Classifications for 436 Distinct Jobs

Exposure Status Job Exposure Matrix (JEM)
Classification
Moderate – High
Exposure
N=120		 Low Exposure
Likelihood
N=316		 Kappa (95% CI)
VGDF 85 (71%) 108 (34%) 0.31 (0.22–0.39)
Exposure Not Reported 35 (29%) 208 (66%)
Irritant Gases or Fumes* 67 (56%) 55 (17%) 0.38 (0.29–0.48)
Exposure Not Reported 53 (44%) 261 (83%)
Biological Materials* 77 (64%) 85 (27%) 0.34 (0.25–0.43)
Exposure NotReported 43 (36%) 231 (73%)
Synthetic Organics* 53 (44%) 46 (15%) 0.31 (0.21–0.41)
Exposure Not Reported 67 (56%) 270 (85%)

VGDF = vapors, gas, dust, or fumes; JEM = job-exposure matrix

Values in Bold = Sensitivity; Values in Bold Italics=Specificity
