I understand that you want to know about ‘evalfis’ function and how to use it. This function takes an FIS and a matrix of input values, where each row of the matrix corresponds to one set of inputs to the FIS. The output of evalfis will be a matrix where each row corresponds to the FIS output for the corresponding row of inputs.
Since you have your data in a table and a fuzzy model called patientfis, you will need to convert the relevant columns of the table to a matrix, run evalfis, and then, if you wish, store the results back into a table.
