Multivariable-adjusted relative risk of colorectal cancer as a function of glycemic load. Data were fit by using a restricted cubic spline Cox proportional hazards model, adjusted for the same covariates as in Table 2. Glycemic load values above the 95^th percentile were deleted to make the graph more stable; knots were placed at the 5^th, 25^th, 75^th, and 95^th percentiles of the remaining observations. Dotted lines = 95% confidence intervals; solid line = adjusted relative risk of colorectal cancer as a function of glycemic load.
