Characteristics for biofilm and biofilm + GF groups of Global category and Global OD variables.

Type	Biofilm Group	(Biofilm + GF) Group
Global OD (Mean ± SD)
Mean ± SD	0.42 ± 0.32	0.21 ± 0.17
(min-Max)	(0.04–1.13)	(0.03–0.59)
Median (CI at 95%)	0.32 (0.16–0.53)	0.12 (0.08–0.27)
Global category
Mean ± SD	3.16 ± 0.94	2.41 ± 1.27
(min-Max)	(1–4)	(1–4)
Median (CI at 95%)	4 (3–4)	2 (1.17–3)

CI = Median Confidence interval at 95%; SD = standard deviation; min = minimum value; Max = maximum value.
