I'm going to assume your point is "Expansion of Medicaid/Medicare did not have as much of an impact as most think, and the results in my quote provide some evidence." Please correct me if I'm wrong. Stage at diagnosis is not independent from healthcare coverage, so adjusting for it loses some information. If people can catch cancers at earlier stages because they gained access to affordable screening, that's a good thing attributable to the expansion. If you'd like to make another point with the stage-adjusted rates, please state it and cite the source.
