Similarly, resistant samples are shown on the right, with those correctly identified as resistant coloured by the tool/panel, those falsely identified as susceptible in red, and no-calls in grey. Note that second-line drugs were not considered in NEJM-2018. E, ethambutol; H, isoniazid; Z, pyrazinamide; R, rifampicin; Am, amikacin; Cm, capreomycin; Cfx, ciprofloxacin; Km, kanamycin; Mfx, moxifloxacin; Ofx, ofloxacin; S, streptomycin.
