  • Data are hazard ratios (95% CIs). Univariate and multivariate hazard ratios with P values and approximate 95% CIs for CRP quintiles as a predictor of development of diabetes. Multivariate analysis included all the covariates regardless of statistical significance on univariate analysis.

    * Analysis using definition of diabetes as two fasting blood glucose measurements ≥7.0 mmol/l;

  • P for the χ2 test on four degrees of freedom for the equality of the five quintiles.
