Tstats for 'Table3' layer 1: overlap not specified: unweighted: effective base used
row/cols
This is in the form nxy, where n represents the category row (the first category row is 1, the second category row is 2, and so on) and x and y are the IDs of the pair of columns.
pval
The p value.

sig

m1, m2
The means in the two columns.

x1, x2
The weighted sum of values in each column (X i).
