  • *

    * Relative risk of developing type 2 diabetes for women with depressive symptoms compared with women without depressive symptoms;

  • calculated using stratified pooled logistic regression with same covariates as in Table 2;

  • calculated using likelihood ratio test by subtracting −2logL for multivariate model with interaction from −2logL for multivariate model without interaction. Test has a χ2 distribution with v degrees of freedom, where v = (dfmodel with interaction) − (dfmodel without interaction);

  • §

    § n = number of nurses in that category at baseline.
