Percentage of viable cells after a 72 h exposure of UCBLs to the waveform 7.8tAM: our results from a previous work [27] combined with those of the present work. Experiments were done six times in our previous work (N = 6) while in triplicate in this work (N = 3). All MF values are peak values. * p < 0.05, ** p < 0.01. Bars denote standard deviation (SD).
