case_images: Reibergrams for IgG, IgA, IgM, and albumin ratios in CSF and serum samples (a) and (b) (see Table 1)
  taken on day 2 (left, CSF/serum sample a) and day 7 (right, CSF/serum sample b), respectively.
  The position of the black square dot within the vertically hatched areas of the right reibergram (day 7)
  indicates a simple progressive disturbance of the blood-brain barrier, i.e., a reduced CSF flow,
  in comparison to day 2 (square dots are displayed within the blank normal area or below the limit).
  It also indicates that there is no intrathecal synthesis of antibodies, which would result in the black square dot
  being displayed within the percentage lines above the dotted line (Reiber, 2016).
