Synergy comparison and correlation analysis of FICI with cefotaxime MIC value decrease. (The synergy testing of baicalein, matrine, and clavulanic acid with cefotaxime in bacterial inhibition showed that different synergy rates, which is the percentage of synergistic strains among the total strains studied, were observed with cefotaxime (a). Correlation between the FICI of baicalein with cefotaxime and baicalein-induced cefotaxime MIC decrease percentage was analyzed using SPSS (b). X-axis denotes the FICI of baicalein with cefotaxime, Y-axis means cefotaxime MIC decrease percentage)
