CTCAE plus supports CTCAE v5.0, v4.03, and v3.0. PREMIUM features help data management and sharing in addition to PLUS features that clarify the CTCAE version difference.


::: Multiple CTCAE Versions :::
CTCAE plus supports multiple CTCAE versions (v5.0, v4.03, and v3.0).

::: Flag :::
Toggle a flag on and off by pulling on a listed event to the right as well as by tapping on a flag.

::: Search :::
Show the search result with the matching text highlighted across terms, grades, and definitions.

~~~ PLUS & PREMIUM (In-App Purchase) ~~~

Once you purchase a PREMIUM/PLUS Pack, you can upgrade and restore CTCAE plus on multiple iOS devices you own — as long as they all use the same Apple ID.

::: Flag+ :::
Based on Term Mapping information, Flags will be taken over from one CTCAE version to another.

::: Search+ :::
Search and highlight multiple strings across terms, grades, and definitions in a primary version. Optionally, 6-color highlight is available.

::: Diff Checker :::
Find differences between two versions with text highlighted in a window.

::: My Note :::
Take your notes which are searchable. My Notes can be taken over from one CTCAE version to another.

::: Mapping Info :::
Visualized Mapping Info can help data conversion from one to another version (e.g. from CTCAE v4.03 to CTCAE v5.0).

~~~ PREMIUM only (In-App Purchase) ~~~

::: Grade+ :::
A numeric grade can be assigned to each tagged AE term. Grading Scale Bars in color or gray help to monitor severity without opening the Detail Window.

::: Search Assistant :::
Search Assistant suggests exploring several sets of related AEs in addition to AND/OR search.

::: Tag :::
Add multiple tags to a single AE term in each CTCAE version. Flagged events can be tagged at once. The tagged events are printable and exportable. Auto Tag Suggestion helps to choose one of the tags previously generated in other AEs.

::: Tile Chart with Tag Bundle :::
The tags containing separator(s) (@ or/and #) can be bundled with the string before the separator. Tap a tile icon to open the Tile Chart window to review the tag-bundled events.

::: Calendar :::
Tap a calendar icon to create an AE info event in Calendar.app.

::: Review :::
Review the tagged AE items in the Review window. Grade scoring is available on each tagged adverse event in the window.

::: Archive :::
Archive and restore Flags and Tags with AE scores. iCloud Sync helps to backup your archival data, copy it between devices, and restore it.

::: Print and Export :::
Report the tagged items through AirPrint, PDF export, Text export, and QR codes.

::: Backup and Recovery :::
You can back up the settings of Flags, Tags, My Notes, and Archives and also recover them.

Sum-IT ,

New version inaccurate

There are far too many errors with the new version. It can be disastrous for patients if this is followed as the only source for grading. Please revise and ensure accuracy to published CTCAE criteria.
