# Trial Time Windows

Use this text field to specify a list of bracketed time values (start and end times separated by commas (,) within square brackets ([]) for each ) that separate the trial into time s. The analysis then incorporates these s. Data occurring outside of the s are not included.

Each must be expressed in the form [s 1,e 1] [s 2,e 2] ... where s x is a numeric start time and e x is a numeric end time. The time unit can be days or weeks as specified in the Time Scale parameter. Each time point is relative to the reference start date for each subject.

If a time consists of a single time unit, you can specify a single numeric value within brackets for that .

Leave this field blank to consider the entire duration of the trial as one large time .

### To Specify a Set of Times:

| 8 | Enter the start and end time for each , enclosed in square brackets ([]), within the text field. Separate start and end times with commas (,).

For example, if you desire to have three time s corresponding to days 2-5, 6-10, and 11-20:

| 8 | Type [2,5] [6,10] [11,20] in the text field, as shown below:
