Figure 4. Relative risks (RRs) for diseases associated with fasting plasma glucose (FPG).

The figure shows RRs for 1 mmol/L higher usual or baseline FPG. The figure shows RRs converted to comparable age group as described in Methods. See Table S1 for RRs in original age groups from each study. The percentage of variation in the pooled estimates that is due to statistical heterogeneity was evaluated using the I² statistic for each age group and outcome. All I² values for these outcomes and age groups were zero.
