Use the figure belоw tо аnswer the next three questiоns relаting to multivаriate relative risks of Type 2 Diabetes Mellitus according to ascending quintiles for cereal-fiber intake, the ratio of polyunsaturated-fat intake to saturated-fat, intake of trans-fat intake, and glycemic load. Image Description Four graphs that look at the multivariate relative risks of Type 2 Diabetes. Graph A The x-axis is titled “Cereal-Fiber Intake,” and it is further divided into five quintiles. The y-axis is titled “Relative Risk,” and it starts at 0.0 and increases by 0.2 until it stops at 1.6. P < 0.001 for trend. Graph A Cereal-Fiber Intake Relative Risk 1st quintile 1.0 2nd quintile 0.975 3rd quintile 0.8 4th quintile 0.775 5th quintile 0.675 Graph B The x-axis is titled “Ratio of Polyunsaturated-Fat Intake to Saturated-Fat Intake,” and it is further divided into five quintiles. The y-axis is titled “Relative Risk,” and it starts at 0.0 and increases by 0.2 until it stops at 1.6. P < 0.001 for trend. Graph B Ratio of Polyunsaturated-Fat Intake to Saturated-Fat Intake Relative Risk 1st quintile 1.0 2nd quintile 0.9 3rd quintile 0.85 4th quintile 0.8 5th quintile 0.8 Graph C The x-axis is titled “Trans-Fat Intake,” and it is further divided into five quintiles. The y-axis is titled “Relative Risk,” and it starts at 0.0 and increases by 0.2 until it stops at 1.6. P < 0.001 for trend. Graph C Trans-Fat Intake Relative Risk 1st quintile 1.0 2nd quintile 1.075 3rd quintile 1.2 4th quintile 1.175 5th quintile 1.4 Graph D The x-axis is titled “Glycemic Load,” and it is further divided into five quintiles. The y-axis is titled “Relative Risk,” and it starts at 0.0 and increases by 0.2 until it stops at 1.6. P < 0.001 for trend. Graph D Glycemic Load Relative Risk 1st quintile 1.0 2nd quintile 1.075 3rd quintile 1.175 4th quintile 1.2 5th quintile 1.4
