If the variable of TG was not taken into consideration, the strongest factor independently associated with steatosis was carriage of the PNPLA3 rs738409 GG genotype (odds ratio [OR]/95% confidence intervals [CI]:2.34/1.557–3.515, P < 0.001), followed by body mass index (BMI, OR/CI: 1.12/1.082–1.167, P < 0.001) and age (OR/CI:1.02/1.004–1.028, P = 0.007) by using the recessive model. Here, PNPLA3 is linked to steatosis.
