Figure 1.

Number of first-time patients from the study practices visiting the Web site.

Note: The figure shows number of visits by first-time patients (y-axis) over time (x-axis) from the 6 study practices; visits by individuals who did not designate these practices as their primary source of care are not counted. The Web site was launched on January 5, 2004, and the patient enrollment period was January 5, 2004, through June 30, 2004. Active efforts to promote the Web site ceased in June, but the visit rate persisted thereafter.
