To calculate E-values, the following SDs for the outcomes of interest were used: 6.01 for the CESD-R-10 score, 5.55 for the GAD-7 score, and 5.49 for the Flourishing Scale score at 1-year follow-up. E-values are reported on the risk ratio scale.

Responses for these 3 categories of SSBs were summed to derive a composite SSB index, ranging from 0 (did not consume any SSBs in the 3 categories) to 21 (consumed SSBs from all 3 categories every day during a usual week) (13).
