Figure 4: Illustrates the distribution of equipment between medical grade power cord and non-medical grade power cord. The boxplot illustrates the difference between protective earth resistance and leakage current values obtained between medical grade power cord and non-medical grade power cords for selected 20 equipment only. Data shown as median (horizontal line), interquartile range (box), 25th to 75th percentile (vertical line). *P=0.000 Non medical grade versus medical grade power cord
