Effect estimates for use of specific pesticides and NHL incidence, adjusting for use of other pesticides*
| Exposed [n (%)] | ||||
|---|---|---|---|---|
| Pesticides | Cases (n=650) | Controls (n=1933) | Logistic regression OR (95% CL)† | Hierarchical regression OR (95% CL) |
| *Each estimate is adjusted for use of all other pesticides listed in table 3, age, and study site. | ||||
| †Odds ratios (OR) and 95% confidence limits (CL). | ||||
| ‡Criteria for inclusion in the models was a pesticide use frequency of ⩾20; however, some pesticide use frequencies are <20 in the multivariable models since observations with missing values were dropped. | ||||
