How do I interpret Missing BMI as a risk factor. In the ML: Neural Networks run BMI Missing was considered a top 10 risk factor. The body text said this about BMI Missing: "This study suggests that missing values, in particular, for routine biometric variables such as BMI, are independent predictors of CVD."
I'm having a hard time wrapping my brain around this concept.
Thanks

It makes sense—if caught early, risk factors like high BMI, high blood pressure, and high LDL cholesterol can be treated and thereby prevent heart attacks and other cardiovascular events.
