Assume that we screen all the estimated 976,848 Hispanic males aged 35 to 64 in Florida for type 2 diabetes using Hemoglobin A1c (HbA1c) test, and the prevalence of diabetes in this group is 12%. Using the data on sensitivity and specificity of HbA1c 6.5% in diagnosing diabetes reported by Karnchanasorn et al. (2016), calculate the following (it is recommended that you set up a 2x2 table [test results x disease status]).
