Scatter plot, best-fit linear line, and the Spearman correlation statistic between the average rating and the subject-specific arithmetic mean (AM) of airborne nickel exposure in the OH and OH/EIQ rounds for plants 1, 2, and 3 (a–c) and each plant’s corresponding distribution of the airborne nickel subject-specific AMs (d–f). OH, assessment based on the occupational history questionnaire only; OH/EIQ, assessment based on both the OH questionnaire and electroplating industrial questionnaire.
