Table 5 Comparison of the agreement between the MSIB and the Reference Standard MSIB (RefS MSIB) to the agreement between the two graders, by cumulative distribution of difference in agreement as well as by Bias and SD
From: Evaluation of a self-imaging SD-OCT system designed for remote home monitoring
