Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Activation of FPA, DLPFC and VLPFC decreased in both groups, but the Tai Chi group's reduction was smaller than the control group's. → Zhang 2026

q3 · i? · causal · r2

Figure-reported fNIRS delta oxy-Hb beta results from the RCT, described in running text: both groups' prefrontal activation fell over the twelve-week intervention, with the Tai Chi group "reduced to a lesser extent" across the six ROIs; no effect size is printed for this descriptive pattern.

"Results in Figure 2 and Figure 3 show that after 12 weeks of Tai Chi exercise intervention, the activation levels of the FPA, DLPFC, and VLPFC regions of the prefrontal cortex in the TC and the control groups were significantly reduced. However, compared with the control group, the activation levels of prefrontal cortex FPA, DLPFC, and VLPFC regions in the TC group were reduced to a lesser extent."
