For the middle two distant bins, a slightly significant difference was observed between LPS coated wire and LPS + PEG coated wire [bin 2 (150–250 μm from edge of wire): LPS RI = 2.31, LPS + PEG RI = 1.37, p = 0.012; bin 3 (250–350 μm from edge of wire): LPS RI = 2.73, LPS + PEG RI = 1.73, p = 0.03].
