Just two weeks ago we released version 3.14 which improved the e-CRF. Today, make way for new statistical features!
Two types of analyzes were particularly requested and have been added to the long list of statistical tests that can be performed with EasyMedStat:
Let's take a look at these new features and how to use them.
Until now, it was possible to perform these analyses on
discrete variables (List or Yes-no). It is now possible to do this for continuous numeric variables.
You will now obtain:
To use this feature, go to “Test variables” then choose the two variables that correspond to your two observers. Next, open the “Assess the interobserver agreement or intraobserver agreement” panel. It's done !
The functionality is available to compare 2 observers or the same observer repeating the same observation twice.
When you compare a numeric variable between more than 2 groups, the test tells you if at least one of the groups is different from the others. However, it does not prejudge the differences between each of the groups.
For this, a post-hoc test must be carried out which will compare 2 to 2 each of the groups, using a p-value adjusted to take into account the inflation of the alpha risk due to these repeated tests.
These post-hoc tests are now automatically performed when you make a comparison of more than 2 groups and the p-value is less than or equal to 0.05:
To use this feature, go to “Test variables” then choose two variables: the 1st corresponds to the numeric variable that we will compare between the groups, the 2nd corresponds to the List type variable which lists the groups. Next, open the “Compare values of …” panel. It's done !
These tests are not performed if the p-value of the main test is greater than 0.05.
