Figure 1.

(A) Liver/spleen ratio (L/S) at baseline and 12 months in participants undergoing sleeve gastrectomy in the subgroup with L/S ratio <1 at baseline, †P < .05 for within-group change. A low L/S ratio indicates fatty infiltration. (B) Change in L/S ratio over 12 months in nonsurgical controls in the subgroup with L/S ratio <1 at baseline. Although all participants in the sleeve gastrectomy group showed resolution of hepatic steatosis 12 months after surgery, only 1 participant in the control group showed resolution of hepatic steatosis.
