a
Based on questionnaire, data for one worker was missing.
b
People who have elevated HDI-IgG are more likely to notice paint on their skin frequently (p<0.05), care less likely to be current smokers (p=0.03), dand are less likely to be wearing supplied air respirators (P < 0.02).
e
All workers who reported wearing respirators also reported having undergone appropriate fit testing.
