Scattergrams of cefiderocol MICs obtained by agar dilution (AD) versus broth microdilution using iron-depleted Mueller-Hinton agar (ID-BMD) for Pseudomonas aeruginosa (A), Stenotrophomonas maltophilia (B), Burkholderia cepacia complex (C), Acinetobacter baumannii (D), and Enterobacterales (E). Lines represent the applied resistance breakpoints: red, investigational CLSI breakpoints (26); blue, FDA breakpoints (29); green, EUCAST breakpoints (16); blue-green dashed line, overlapping EUCAST and FDA breakpoints.
