 Odds ratios and 95% confidence intervals for use of cellular or cordless telephones

>1 year latency>5 year latency>10 year latency
Ca/CoOR95% CICa/CoOR95% CICa/CoOR95% CI
Number of exposed cases (Ca) and controls (Co) is given. Dose-effect calculations were made with median number of hours for controls as cut-off. Unconditional logistic regression adjusted for age and sex. Unexposed group consisted of cases and controls with no exposure to cellular or cordless phones.
