Variables with * used for adjustment in final model.
**
General Linear Models, contrast test for trend, F(df=1,3139).
However due to missing values in some variables, number varies slightly for each GLM model.
***
T-tests: df described in the table.
If variances between the two groups were not significantly different, we used Pooled method for t-tests.
If variances between the two groups were significantly different, we used the Satterthwaite method for t-tests.
