Comparison of banding calls and diagnostic calls from two experienced readers of MTBDRplus done on serial dilutions of M. tuberculosis .

	Ramp rate (°C/s)
	2.2 (%)	4.0 (%)
Banding calls
Different band calls between readers for susceptible strain	0/198* (0)	2/198 (1) (p = 0.156)
Different band calls between readers for resistant strain	1/198 (0.5)	6/198 (3) (p = 0.057)
Diagnostic calls
Susceptible strain correctly classified by both readers	18/18 (100)	16/18 (89) (p = 0.146)
Resistant strain correctly classified by both readers	18/18 (100)	16/18 (89) (p = 0.146)

^*22 bands per strip × three dilutions × three replicates = a total of 198 bands.

P-values are for within-row comparisons between different ramp rates.
