The mean percentage duration (%) of each phase is displayed with its standard deviation for both the groups and the ventricles. The right column for both ventricles contains differences in percentage distribution of the phases in the state diagram between the NSTEMI group and the control group. The level of significance is illustrated with annotations (* p < 0.05, ** p < 0.005).
