Box and whisker plots showing the baseline levels of six biomarkers as a function of five indicators of baseline disease state: presence of cavities in chest x-ray, presence of cavities > 4 cm, lung involvement > 50%, smear grade (≤ 1 vs ≥ 2) and time-to-detection (≤ 5 days vs > 5 days) for MGIT cultures. The asterisks indicate that the difference between two groups is significant (p < 0.05/62 assays = 0.0008).
