Correlation of test results with clinical outcome
During the clinical evaluation of antimicrobial agents, clinical
cure and bacterial eradication rates must be correlated with
appropriate in vitro tests results to con¢rm the validity of the
proposed interpretive criteria.There may be occasions when a
clear breakpoint can be determined from the clinical data. In
other situations, the clinical data will serve more to support
other types of data (microbiological and pharmacokinetic/
pharmacodynamic) in determining interpretive criteria.
