Observed and predicted relapse rates in the treatment shortening study of Johnson et al [9].

Predictions were based on updated model parameters, a month 2 culture positive proportion of 0.005 (0.5%), and a sample size of N = 185 per arm. H = isoniazid; R = rifampin; Z = pyrazinamide; E = ethambutol. Observed and predicted relapse rates in the treatment shortening study of Johnson et al [9].
