For almost all conditions tested, intra-examiner data showed that the difference calculated for Pz-sap values between the two measurements were numerically smaller when three colonies per sample were analyzed (data notshown).
The criteria proposed by Fermanian32 suggest that ICC values ≥ 0.71 can be considered as “Good reproducibility.”
Figure 1 shows that the majority of protocols with this level of reliability was performed with triplicate readings, especially for E1, E2, and E4
