Shows how electronic data were transferred from each Cancer Research Network site (Marshfield and Group Health) to KPCO (Kaiser Permanente Colorado) before transfer to VARI (Van Andel Research Institute). Vermont transferred data directly to VARI. Data were routed through the VARI FTP (File Transfer Protocol) server and underwent initial validation before transfer to the BRCASO database.
