Figure 2 Nomograms for approximation of body weight and recombinant tissue plasminogen activator (rt‐PA) dose for acute stroke. (A) Nomogram for male patients. (B) Nonogram for female patients. How to use: identify the patient's body height, and waist and hip circumference on the respective scales; read the number of points given from the topmost scale and note in the box to the right for all three parameters; the sum of the points is calculated and identified in the topmost scale of the lower part of the nomogram; the corresponding body weight and rt‐PA dose can be read on the scales below. The validated range of input variables is marked with a horizontal line over the scale.
