QTc Interval Normal Range: 320–440 msec.

QTcI, Individual subject corrected QT interval; SD, Standard deviation; SE, Standard error; LS, Least squares; CI, Confidence interval; Min, minimum; Max, maximum.

a

Baseline is the mean of all technically adequate recorded values from 3 h predose to immediately predose.

b

Postdose value from +1 min to +1 h where the maximum increase from baseline occurred.

c

Based on an ANOVA model including dose and period as fixed effects and subject as random effect.
