Daily log10 colony-forming units (log10CFUs) and log10 time to positivity (log10TTP) for mycobacteria over 7 days for all 59 participants. The relationship between TTP and CFUs is determined using an ordinary least-squares regression model: TTP = b0 + b1 × CFUs. The resulting equation is log10TTP = 2.663 – 0.0854 × log10CFU; r2 = 0.555; P < 0.0001 for b0 and b1.
