Screenshot of the web page for clinical data (http://www.vwf.hemobase.com), showing the patient-specific clinical and coagulation variables (blood group, laboratory coagulation parameters, symptoms, sex, geographical origin, etc.). The related molecular data (A) and family tree with inheritance information (B) can be easily consulted from this page by direct access with pop-up windows. The emergent molecular data table summarizes the significant information about the mutation(s) found in the patient. In addition, there is a link to PubMed entries of the articles reporting this variant. The website was built using the template-based website design tool RapidWeaver 4.1 (Realmac Software). The VWF database was developed using MS Access software (Microsoft Corporation), and ASPRunnerPro (Xlinesoft), a database management tool, was used to create a set of Active Server Pages to access, modify, display, and navigate the data on the web.
