Cox regression results for lymphoid cell line tumours*
| Analysis, exposure variable | Model likelihood, df, p value† | Coefficient (SE) | Odds ratios by category‡ |
|---|---|---|---|
| *Lymphoid cell line tumours include NHL, myeloma, and lymphocytic leukaemia (ICD 9th revision codes 200, 202, 203, 204 (53 cases, 27 male, 26 female). Cox regression, cases and controls matched on age, race (white/non-white), date of birth within five years. | |||
| †Model likelihood is difference in −2 log likelihoods between model with and without covariates; the only covariate in these models was exposure, so the p value of the model serves as a test of significance of the exposure coefficient, and as a test of exposure-response trend. | |||
| ‡Categories for cumulative exposure are the same as in tables 2–5. | |||
