Variation in acidification and proteolysis activities in hMDM from PTB (n = 60) and TBM (n = 64) in response to TDM beads.

Acidification	30 min			60 min			90 min
	Range	% CV (mean ± SD)	P	Range	% CV (mean ± SD)	P	Range	% CV (mean ± SD)	P
PTB	0.98–1.09	2.69 (1.03 ± 0.03)	0.78	1.02–1.23	4.59 (1.11 ± 0.05)	0.66	1.02–1.32	4.83 (1.14 ± 0.06)	0.77
TBM	0.98–1.1	2.77 (1.03 ± 0.03)		1–1.22	4.3 (1.1 ± 0.05)		1–1.27	5.01 (1.13 ± 0.06)
Proteolysis	60 min			120 min			180 min
	Range	% CV (mean ± SD)	P	Range	% CV (mean ± SD)	P	Range	% CV (mean ± SD)	P
PTB	1.31–5.4	29.3 (2.97 ± 0.87)	0.28	3.59–14.96	32.08 (8.47 ± 2.72)	0.35	6.14–19.74	28.51 (11.81 ± 3.37)	0.35
TBM	1.09–4.85	34.2 (2.79 ± 0.95)		1.74–15.30	37.13 (8.21 ± 3.05)		2.31–21.27	32.85 (11.78 ± 3.87)

PTB, Pulmonary tuberculosis; TBM, Tuberculosis meningitis Range, min-max; Mean ± SD, Mean ± standard deviation; CV, coefficient variation, calculated by percentage of SD divided by mean. P, P value for comparison of coefficient variation in either acidification or proteolytic activity among two groups.
