Please be aware that this tool is to enter, calculate and analyze data collected by you. It does not produce a "magic" answer. The decision as to which method to use in any given patient is left up to you. We are not responsible for clinical results in any given patient.
You will be downloading an Excel Template File (*.xlt). Double click on it and Excel will open it and give it a name ending in *****1. Enter your data for patient #1 and then when you close it or save it, Excel will prompt you to Rename it: use the patient's name. The next time you click it, it will be named *****2, etc. The Main xlt file will not be changed.

Always check the website for updates

NA has been entered in every cell for which there is no data. Click on the Tab "Example Tool" to see what it looks like when you have all possible data (see chart below.) Always leave NA or enter NA where there is no data or the spreadsheet will not work correctly.
