Considering the strong association between NAFLD and insulin resistance, and the vital role of insulin-like growth factor 1 (IGF1) in IR, we hypothesized that IGF1 gene polymorphism might be associated with NAFLD.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>A total of 302 subjects, including 149 patients with biopsy-proven NAFLD and 153 controls, were enrolled in this case-control study.

The IGF1 rs5742612 CC genotype compared with the TT genotype or the TT+TC genotype occurred more frequently in the cases than the controls and the differences remained significant after adjustment for confounding factors such as age and body mass index (P\u2005=\u2005.011, OR\u2005=\u20052.71, 95%CI\u2005=\u20051.16-5.85; and P\u2005=\u2005.032, OR\u2005=\u20052.29, 95% CI\u2005=\u20051.10-5.24,
