C
value of 0.00 was obtained with a
95% confidence interval of (-0.28, 0.28), indicating no significant
difference between the candidate and reference methods. A dPOD
CP
value of 0.00 was obtained with a 95% confidence interval of (-0.28,
0.28), indicating no significant difference between the candidate
presumptive and confirmed results.
