Δ, Change. Columns 1-4 illustrate the percentages of 4 kinds of dyads at different time levels. Column 5 shows the percentages of the combination of the +HbO/−Hb and −HbO/+Hb dyads. Columns 6 and 7 describe the linear relationship between [HbO] and [Hb] changes in terms of the Pearson correlation coefficient and slope.
