Different measures of growth rates of the three Mycobacterium tuberculosis metabolic populations

Assay (unit)	Log-phase growth bacteria (95% CI)	Semidormant bacteria (95% CI)	NRP cells (95% CI)
Live/dead slope (RFU/h)	60.72 (33.76–87.68)	7.48 (3.06–11.90)	4.72 (−0.56–10.01)
OD600 (×10−4 units/h)	20.79 (12.03–29.55)	1.98 (0.35–3.62)	1.12 (−0.48–2.73)
Log10 CFU/ml/day (slope)	0.069 (0.059–0.079)	0.013 (0.007–0.018)	0.005 (0.001–0.009)
Ribosomes/CFU (10−5)	4.021 (3.204–4.838)	2.555 (1.340–3.770)	1.723 (1.294–2.153)
