Imaging studies often examine the brain over long periods of time to see how the neural structure and functions are affected by age, treatments, disease progression or any other variables.
To browse the overview of variables over time, we introduced "Longitudinal statistics" which allows plotting the correlation between any variable and the sessions of image acquisitions. You can get the figure with one click, without installing or maintaining any statistical software.
Open Longitudinal statistics
- Click My Data
- Click Longitudinal statistics
- Select a field for X-Axis (e.g. Ordered timepoint to browse the evolution of Y-Axis variable over time)
- Slect a field for Y-Axis (imaging biomarker or clinical scores)
- Click Show
When you want to use cumulative values in X-Axis, check "Cumulative X"
A scatter plot is automatically generated with a regression line.
You can select the method of regression; linear (straight), exponential or polynomial.
When you filter data in My Data, that filter is applied to Longitudinal statistics too.
- Add a field to set search criteria if it is not listed
- Enter search criteria
- Click Search
Then, open Longitudinal statistics to make a plot with filtered data.
Filtering applies to any new plots which are subsequently created, existing plots will not be lost.
