  • a Twenty pairs of acute-phase (A) and convalescent-phase (B) sera from SLE-infected individuals were tested.

  • b The cutoff for positivity for NS5 is 4,366. There were 2 positive samples out of 40 (5%).

  • c The cutoff for positivity for E protein is 1,084 (Wong et al., submitted). There were 11 positive samples out of 40 (28%).
