Looks like something interesting is going on with IFNg by frailty, poverty status, & race. These differences aren't apparent looking at race or poverty status separately with frailty. These differences become apparent because there's a 3-way interaction among frailty, poverty status, & race (and -- not shown -- these effects are not apparent in just poverty status by race).
