Fig. 2. Replicability and Precision Analysis through measuring operator-to-operator and repeated run experiments.

(A) Operator Variability: Three samples were run in duplicate by two different operators to assess both the variability in operator handling as well as repeatability from the same operator. The 12CK GES showed low variability across operator whereas the RSI score had a larger difference in RSI score between operators. (B) Repeated run over time: Four samples were repeated one week apart and assessed. The variability in the 12CK GES was low for all samples. RSI showed variability (less than 0.1) in two of the four samples.
