We are able to then use the BMI formulation to calculate the BMI for every time level and plot the outcomes utilizing a scatter plot or line graph.
BMI at Month 1 = 70 kg / (1.65 m ^ 2) = 22.2
BMI at Month 2 = 72 kg / (1.65 m ^ 2) = 22.3
BMI at Month 3 = 74 kg / (1.65 m ^ 2) = 22.4
BMI at Month 4 = 76 kg / (1.65 m ^ 2) = 22.5
BMI at Month 5 = 78 kg / (1.65 m ^ 2) = 22.6
BMI at Month 6 = 80 kg / (1.65 m ^ 2) = 22.7
The scatter plot or line graph will present the pattern of the affected person’s BMI over time, permitting us to trace adjustments of their weight standing and make knowledgeable selections about their care.
