Results were attenuated with the inclusion of the variables in model 2 and further so with the inclusion of covariates that directly affect average GI in model 3, yet participants in the fourth and

The inclusion of the variables in model 2 attenuated the associations, with the result that only

Being in
the fifth quintile for both measures may be a good sign for performance, but I would not put too much confidence in that.
