Hi,
I have 3 columns with dates of different types imaging tests done in a timeframe.
I'd like to see if an individual had done AT LEAST 1 of the 3 different methods in this timeframe.
For example: I have entries for US, CT and MRI at baseline. An individual could have done US and MRI = yes at least 1 method. If the person did not have done any imaging test, it would be = no for at least 1 method.
But I'm not finding an easy way to understand how to compile this information in 1 single column.
Thanks in advance
