  Figure 2.. Nomogram to estimate the risk of CAD. To estimate the risk of CAD, first identify the value for each axis, and then draw a vertical line upward to the point axis from the axis for each factor. Sum up the points for all factors and locate the value on the total point line. Subsequently, draw a vertical line down to the risk of CAD. For example, the factors of male sex (100 points), hypertension (85.5 points), diabetes (48 points), absence of dyslipidemia (0 points), ischemic stroke (75 points), and ALI ≤39.29 (57.5 points) result in a total of 366 points, which gives an estimated probability of 94% for the occurrence of CAD.

  Figure 4.. Nomogram to estimate the risk of CAC. To estimate the risk of CAC, first identify the value for each axis, and then draw a vertical line upward to the point axis from the axis for each factor. Sum up the points for all factors and locate the value on the total point line. Subsequently, draw a vertical line down to the risk of CAC. For example, the factors of male sex (100 points), hypertension (72.5 points), absence of diabetes (0 points), dyslipidemia (67.5 points), ischemic stroke (81 points), and ALI ≤39.29 (48 points) result in a total of 369 points, which gives an estimated probability of 92% for the occurrence of CAC.

  Figure 6.. Nomogram to estimate the risk of CAD with CAC. To estimate the risk of CAD with CAC, first identify the value for each axis, and then draw a vertical line upward to the point axis from the axis for each factor. Sum up the points for all factors and locate the value on the total point line. Subsequently, draw a vertical line down to the risk of CAD with CAC. For example, the factors of female sex (0 points), hypertension (87 points), diabetes (63 points), dyslipidemia (67.5 points), and ALI ≤39.29 (48 points) result in a total of 265.5 points, which gives an estimated probability of 77% for the occurrence of CAD with CAC.
