PLA2G7 and diabetes mellitus: Subgroup analysis for DKD showed that heterogeneity reduced to zero in cross-sectional studies, among those with <30% prevalence of DKD, and among those reporting adjusted data, but results also became non-significant across multiple subgroups.<h4>Conclusions</h4>Limited evidence indicates that high Lp-PLA2 may be predictive of DKD in DM patients.
