Figure 1.
Association between bleeding symptoms and VWD diagnosis using multivariable logistic regression with backward elimination. The number of subjects with clinically significant scores in each category is listed in parentheses. For each bleeding symptom, the graph reports the odds ratio and its 95% confidence interval. Significance was set at P < 0.05. Having clinically significant bleeding scores for the symptoms of CNS bleeding and muscle hematoma did not significantly increase the odds of a VWD diagnosis. The Hosmer and Lemeshow test of the goodness of fit suggests the model is a good fit to the data as P = 0.13. The Cox and Snell R 2 was 0.378. The unit for age is increasing decades of years. Female sex was set as the reference category. Please note that the x‐axis is not to scale. CNS, central nervous system; VWD, von Willebrand disease
