A scatterplot of MIF levels in the 5 groups is shown in Figure 5A. Mean plasma levels (ng/ml) were significant higher in 35 new-onset DM PC patients (32.1 ± 9.6) compared with 35 non-DM PC patients (17.3 ± 6.4, P <0.001), 35 long-term DM PC patients (20.4 ± 6.6, P <0.001), 35 normal fasting glucose healthy people (14.3 ± 5.8, P < 0.001), and 35 new-onset T2DM patients (21.8 ± 7.57, P <0.01). This evidence concerns the gene MIF and diabetes mellitus.
