The results also found a significant beneficial effect of the active intervention for several secondary cognitive outcomes such as Digit Symbol Substitution Test score, and the mean difference between groups in the ITT analysis was 2.72 (95% CI: 0.20, 5.23).

Posterior estimates indicated that CAF+TAU was associated with a credible positive effect on anaerobic capacity (g = 0.46, 95% CrI [0.19, 0.71]) and reaction time (g = 0.75, 95% CrI [0.29, 1.18]) compared to CAF or TAU alone.
Rests on two meta-analyses that state the dose range they cover. One (PMID 29546641, 10 studies, single doses or up to 2 weeks of 1 to 6 g a day) found endurance improved (Hedges' g 0.40) and that the dose did not change the size of the effect. The other (PMID 40852891, 23 randomised trials of a single dose, 308 participants) found a small-to-moderate overall gain (g 0.25, I² 61%), no significant dose-response within 1 to 6 g, and rated the certainty low to very low. So the curve is flat from 1 g to 6 g. No minimum, optimal or ceiling dose is set, because neither abstract reports an effect or safety at a single dose within the range.
