Statistics is based on the segmentation labelmap as you are seeing in the 2D slice view. What you’re showing in the 3D view is the segmentation with a smoothing factor applied for display purposes only. It is not removing actual features in the segmentation.

See the below post from another thread

> Surface smoothing is required for reconstructing a continuous surface mesh from discrete samples stored in a labelmap volume. This smoothing does not remove any details from the segmentation. If you set surface smoothing to 0 then you will see the discrete samples instead of the reconstructed surface (each voxel of the labelmap will appear as a cube). Smoothing effect is for removing irrelevant details (i.e., surface noise, speckled, small holes) from the segmentation.
