Table 6 Linear multiple regressions for determinants for serum concentrations of CB-153 (ng/g lipid) and p,p'-DDE (ng/g lipid) among Swedish fishermen and their wives.a.

From: Inter-population variations in concentrations, determinants of and correlations between 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p'-DDE): a cross-sectional study of 3161 men and women from Inuit and European populations

  1. a) The β-coefficients (with 95 % CI within brackets) are shown.
  2. b) The variable did not fulfil the criteria to be included in the final model.
  3. c) n.a = not analyzed because data was not available.
  4. d) Cumulative explained variance after successive addition of determinant variables to the final multivariate model. Thus, the total explained variance is given on the lowest line.
