  1. Coefficient (Coef.) of the cumulative exposure (Dose) to DEE in μg/m3-years and absolute term (Constant) with standard deviation (Std.Err.); t-test statistic for the coefficient with the corresponding P-value and a 95 % confidence interval for the coefficient, 95 % CI. The figures in parentheses are the results when using the standard normal distribution
