What is the association between sex and mortality rates in patients with CVT?
No association between sex and mortality rates was seen in the recent Nationwide Inpatient Sample of 3488 patients; however, the mortality was higher in that cohort (4.39%), which contained a surprisingly large number of patients with CVT. In a larger sample of 11400 records from the Nationwide Inpatient Sample data set, the most common condition associated with CVT was pregnancy/puerperium (seen in 24.6% of patients). Logistic regression analysis confirmed that the absence of sex-specific risk factors was a strong and independent predictor of poor outcome in women with CVT (OR, 3.7; 95% CI, 1.9 7.4). Although there was a trend toward higher mortality in males, this was not significant.193
