Table 2. Linear regression coefficients of determination (R²) calculated from the parameters measured in Staphylococcus spp. strains biofilm producers and non-producers.

At least five sampling points along the incubation time were used for the linear regression calculation (see in supplementary material “S1 Fig” the linear regression equations calculated for the biofilm producers).

			Linear regression coefficients (R²)^*
Species	Strain	Biofilm forming ability	CI vs. Abs	CI vs. Log CFU	Abs vs. Log CFU
S. aureus	15981	Biofilm producer	0.9860	0.9707	0.9529
	ISP479r	Biofilm producer	0.9558	0.9692	0.6908
	132	Biofilm producer	0.8828	0.9719	0.9849
	V329	Biofilm producer	0.9393	0.9605	0.9873
S. epidermidis	F12	Biofilm producer	0.9413	0.9521	0.9814
S. aureus	CH1368	No-biofilm producer	0.1128	0.5074	0.0116
S. epidermidis	CH48	No-biofilm producer	0.1895	0.6201	0.0171

* CI, cell index; Abs, absorbance; CFU, colony forming units.
