a
The incidence of elevated titers is given as number of seropositive cases (above the respective cutoff), using the earliest serum samples available. Significant differences between patients and controls (Fisher’s exact test) are indicated as follows: ****, P < 0.0001; ***, P < 0.001; *, P < 0.05.
b
Total number of seropositive cases in any of the three Ig classes/total number of patients.
c
CON, healthy controls.
