MuSK autoantibodies positive patient sera listed according to RIA values.

The table provides data from Figure 4. MuSK autoantibody positive patient sera are shown for HEp-2 M4+ESM and HEp-2 M4−ESM. The sera are sorted to descending RIA values (RIA cut off: >50 pmol/L positive, >500 pmol/L strong positive). The value X¯ describes the mean value of positive cells related to total cell number which is combined with standard deviation (±SD) and semi quantitatively scored fluorescence intensity (FI). The p-values are given for HEp-2 M4+ESM compared to HEp-2 M4−ESM (p1) and HEp-2 M4−ESM compared to HEp-2 cells (p2). N.v.: not valuated because FI was negative, n.a.: not available due to negative FI.
