Distribution of FIC values in isolates producing different carbapenemase. Horizontal and longitudinal axes represent the type of carbapenemase and the proportional scaler, respectively. The red, blue and green boxes represented the FIC values of <1, 1 (inclusive) ∼2 and ≥2, respectively. P < 0.05 means that there was statistical difference. P value calculated between carbapenemase pairs that exhibited significant difference (P < 0.05) in the checkerboard synergy testing were labeled on the top.
