Thresholds (median and quartiles) for treatment of smear-negative PTB calculated by four different approaches. Regret-based holistic: threshold calculation on the basis of regret estimations of omission and commission on a Likert scale (pure regret based). Utility-based clinicians’ estimates: threshold based on clinicians’ intuitive estimates for disease and treatment morbidity and mortality without clinicians’ regret. Utility-based literature: threshold based on literature data for disease and treatment morbidity and mortality without clinicians’ regret. Hybrid model: threshold based on clinicians’ intuitive estimates for disease and treatment morbidity and mortality combined with clinicians’ regret for death by omission or commission.
