Sensitivity analysis
Sensitivity analysis was conducted in clearly-defined GDM patients and
not clearly defined GDM patients respectively.The findings were not
statistically different, with a pooled effect estimate of 1.10
(95%CI:1.04, 1.17) in clearly-defined GDM patients studies and
1.19(95%CI:1.10, 1.28) in undefined GDM patients studies. It indicated
the reliability of the studies included in this meta-analysis. A fixed
effect model was uesd in clearly-defined GDM patient studies to show the
heterogeneity of the studies with (I2 =57.2%,
P=0.009) and a random effect model in undefined GDM patients studies
(I2=67.4%, P=0.000). (Figure 5)
