MIC S. ATCC = 1.74 − 1.46 × 10−3 × TAC + 2.69 × 10−4 × ORAC 1.00 0.002
MBC E. UTI = 3.64 + 5.83 × 10−3 × TAC − 6.00 × 10−4 × ORAC 0.99 0.023
MBC S. ATCC = 5.64 + 3.62 × 10−3 − 1.12 × 10−3 × ORAC 0.99 0.033
MBC E. UTI = 2.03 + 4.33 × 10−3 × TAC 0.92 0.039

Where: The first letter in the abbreviation stands for the variable correlated: MIC—minimum inhibitory concentration; MBC = minimum bactericidal concentration; the letters afterwards show the strain tested: E.—Escherichia coli; S.—Salmonella Enteritidis; while the type of isolation is last: UTI—strain isolated from urinary tract infection; ATCC—standard strain.
