Filter properties

In this dialog box you can define a filter and give it a descriptive label.

Define a filter

Filter

In the top input box you can enter the formula for the filter.

E.g. if you have a variable named TREATMENT containing codes (0, 1) for the treatment given to patients, you can enter a filter as follows:

TREATMENT=0

You can combine different criteria into one filter using the AND() and OR() functions (see Logical functions). Click the Filter properties button to call the Filter formula editor for easy editing of the formula.

Label

Next you can enter a descriptive label for the filter. This label will be displayed in reports and graphs.

For example:

Placebo
