Figure 5.

Contribution of LF and GF to sulcal width (A) and depth (B). Local factors (LF); global factors (GF). The R-squared changes (ΔR²) indicate changes of explanatory power between models with and without LF or GF (proportion of variability of the sulcal measures explained by LF or GF). *Indicates significant association (p < 0.01) between LF or GF and sulcal width or depth. Error bar shows 95% confidence interval, which indicates significant differences (95% confidence interval not overlapping) between LF and GF in explaining sulcal width/depth.
