Association of HbA1c on seroprotection and seroconversion in the year 1 cohort. HAI titers were measured in response to A/Brisbane/59/2007 (A,D), A/Brisbane/10/2007 (B,E) and B/Brisbane/60/2008 (C,F). The line shows the least squares regression of the relationship of HbA1c to HAI antibody levels seroprotection (A–C) and seroconversion (D–F). Increasing HbA1c levels only increased the odds of seroprotection against A/Brisbane/10/2007 (B).
