Construct the 2 by 2 table for CMZ test the gold standard when a cutoff of >41 units is used for classification ( equal or greater).
There are 6steps for creating 2 by 2table for CMZ test:
- create a observation frequency
- calculate the column and row total
- calculate the expected frequency
- calculate the sum difference
- compare the values
In gold standard number of not infected patients 359 +186+75+2+-0= 622
Total number of Qpox infection Patient 0+5+32+41+89 = 167
0-20=359
21-40= 191
41-60 = 107
61-80 = 43
81- 100= 89
Total = 789
They used cutoff>41 units for the combination of CMZ test and gold standard..it was normal after cutoff >41units..
It is equal
