When you have logged in, you will first be asked to select your user group for this particular session. There are separate sets of case studies appropriate to each user group, although all users have access to all available cases.
Selecting a group then takes you to the "Case Studies" page for that group. Thereafter, the 'workflow' should be self-evident from the tabs across the top. Tabs become progressively available (or unavailable) as you progress through a case.
Click on a case to select it.
You will then move to the next page of the website, which displays relevant history and physical findings. You can use the tabs at the top or arrows at the bottom of the page, as available, to progress through the case.
Using the back/forward buttons in your browser is not recommended, as these may yield unpredictable results.
Note that new cases will continue to be added to iNvestigate in the future.
