The author regrets that ICC reported in the abstract and the discussion for the modified RAIL by ELISA vs MPL was reported incorrectly. It should be 0.68 with 95% CI 0.62-0.74.
In addition, there was an error in Table 3. In column one, the last two labels are switched, should be “Modified RAIL MPL vs ELISA” then “Original vs Modified RAIL”.
The author would like to apologize for any inconvenience this may have caused.
