Threshold analysis of parameters at which the costs of SMS intervention and control became equivalent over a 50-year period.

Parameters	Base-case	Threshold
SMS intervention cost at year 1	$34.38	$1,704.04
SMS intervention cost at year 2	$7.64	$3,093.78
Annual transition probability
From IGT to T2DM, SMS at year 1	3.53%	12.22%
From IGT to T2DM, SMS at year 2	6.25%	22.60%

Note: IGT = impaired glucose tolerance; T2DM = type 2 diabetes mellitus.
