Meaning of the red and green color data points in NCA>Slopes Selector

Hi All,

I have a very basic query. I am trying to figure out the meaning of green and red color datapoints in “Slopes Selector” after running an NCA (NCA_202).

Does these colored data points (green and red) refer to 1st and last data point used in calculation of t1/2 in NCA?. If this is the case, when I exclude last data point (t=24) from the calculation of slope (NCA_201), the 12 hr data point does not change to red color.

Thank you,

Hari.

Dear Hari,

your assumption regarding the colored data points in the Slope Selector is right. Changes of the display after excluding a data point are sometimes lagging. It should update the display when you switch between different profiles or when you do a fit and then go back to the Slope Selector.
