Table 4. Biased odds (OR′) ratios according to sensitivity and specificity of the job exposure matrix when the true odds ratios (OR) were assumed to equal 1.5, 2 or 3.

¹Prevalence of exposure is assumed to equal 0.50.

²Prevalence of exposure is assumed to equal 0.33.

³Prevalence of exposure is assumed to equal 0.25.

*Statistical significance at the 5% level (two-sided test) of the biased odds ratios is calculated for a study population of 5000 men and 5000 women.
