a
Mean change in TER between zero time and 6 h, expressed as a percentage of the TER at zero time. The values in parentheses are standard errors of the means.
b
Change in TER expressed as a percentage of the E2348/69 change in TER.
c
+, significantly different from E2348/59 at P values of <0.05, as determined by a single-tailed t test.
