QTc, corrected QT interval.
#P < 0.05, ##P ≤ 0.04, ###P ≤ 0.01.
SB50: bradycardia <50 b.p.m.; SB60: bradycardia <60 b.p.m. SD, standard deviation.
Unless stated, values represent absolute numbers of patients (percentage of patients).
The table shows the ECG abnormalities on the ECGs obtained shortly after SCI and at 4 weeks.
