Table 1 Distribution of clinically and genetically relevant variables in a cohort of women at baseline of the observational period 1993 – 2003. The total number of women in this analysis is 4320, i.e. excluding 17 women with a final diagnosis of a possible/potential VTE. Deviations from this number are due to missing information

From: Comparison of incidence/risk of venous thromboembolism (VTE) among selected clinical and hereditary risk markers: A community-based cohort study
