Steenland et al. [2]: Linear regression with fixed effects for log RR with weights proportional to the inverse of the respective variance

Log RR	Coef.	Std. Err.	t	P	95 % CI
Dose	0.00096	0.00021	4.55	0.045 (<0.001)	0.00005 (0.00055	0.00187 0.00137)
Constant	−0.031	0.070	−0.45	0.70	−0.33	0.27

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
