T. Liu et al. aimed to explore the potential link of serum vitamin D level with NAFLD. Of the 309 initially retrieved studies, 15 studies of high quality involving a total of 20 096 participants (including 7803 NAFLD patients) were included in this meta-analysis.
Meta-analysis of continuous data indicated that NAFLD patients had lower levels of 25-hydroxyvitamin D compared with the non-NAFLD subjects. Serum vitamin D level is negatively associated with NAFLD. Patients with hypovitaminosis D might benefit from extra supplement of vitamin D against the risk of NAFLD
