Those don't have periodontitis

People with gum disease are almost twice as likely to suffer from coronary artery disease compared to those don't have periodontitis.

Why would it be correct to say those don't have periodontitis, not "those who don't have periodontitis" or "those that don't have periodontitis"?

Generally speaking you should use "who" when referring to people.

Only half of your examples actually use "those that" to mean "those who". The second and third aren't referring to people. What can I say about the first and fourth? I find the use of "those that" rather than "those who" jarring when talking about people, and I'm not alone - and you're always on safe ground if you use "who" to refer to people.
