Figure 4. The effect of energy reduction and calcium supplementation on FSG, and 2h-glucose adjusted for age, gender, smoking, drinking, regular exercise, and BMI. (A) Comparison of FSG changes between ERGs and NERGs. (B) Comparison of FSG changes between CSGs and NCSGs. (C) Comparison of FSG changes among CG, ERG, CSG, and ER-CSG. (D) Comparison of 2h-glucose changes between ERGs and NERGs. (E) Comparison of 2h-glucose changes between CSGs and NCSGs. (F) Comparison of 2h-glucose changes among CG, ERG, CSG, and ER-CSG. Note: P-value for the difference in the joint effect of intervention and time.
