^aTime constants are as reported in Figures 2, 3, and 4 and are indicated within each subtable. For Figure 4, the protocol is referenced in square brackets. Lower case letters indicate significant differences for any one time constant at P < 0.01. Upper case letters indicate significant differences for any one time constant at P < 0.001.
