Reliability assessment of sub-sampling manual ICV estimation. Left: 5^th, 25^th, 50^th, 75^th, and 95^th percentiles of the empirical distribution of Intra-class Correlation Coefficient (ICC) are plotted for each group contrasting the estimated ICV based on a specific sampling rate with the estimated ICV considering every slice protocol; Right: Maximum Percentage Error (MPE) are given for groups. ICC of 0.99 is highlighted in ICC plots and the corresponding sampling period is found as the point could be considered as a reference to not to lose the accuracy when using subsampling strategies. The sampling period corresponding to the ICC of 0.99 is marked to assess the MPE for that specific sampling period.
