Leaflet	1.180 ± 0.404	0.412 ± 0.087	2.605 ± 0.759	1.304 ± 0.525
Sinus	1.476 ± 0.673	0.589 ± 0.429	3.995 ± 0.665	1.273 ± 0.190
Artery wall	3.133 ± 0.777	0.681 ± 0.103	1.982 ± 0.760	0.905 ± 0.074
Pericardium*	0.017	*	*	80.289

*Single data regarding C4S/C6S and D4S/D6S for pericardium were very high, as 6-sulfation was near to 0.
