Browse Categories I - select
Since the example research question concerns knee symptoms and physical activity, we will select these categories and browse through all the related variable labels.
1. Select "Knee symptoms" from the list by clicking on it.
2. Scroll down to "Physical activity," press "Ctrl" and then select "Physical activity" by clicking on it.
You now have both categories selected.
3. All the visits available are selected by default. Leave this as is for our example, but note that in the future you can uncheck visits to filter your results.
4. Click the "Search/Browse" button to generate a longitudinal display of the selected categories.
