Table 1.

Crude and adjusted odds ratios with 95% confidence intervals (CIs) of screen-detected, interval, and subsequent screen-detected cancers in BreastScreen Norway. The exposure variables (interpretation score and outcome of consensus) were modeled separately. The adjusted models accounted for age and prevalent/incident attendance
