Tate 2019 VACS Index 2.0 (not 1.0)

Tate 2019 VACS Index 2.0 (not 1.0): age, CD4, HIV-1 RNA, hemoglobin, caller-assigned FIB-4 and eGFR, hepatitis C, albumin, WBC, and BMI. Appendix Table 1 polynomials. Score scaled so the median profile is 44. Not a 5-year percent (no published S0). magent does not compute FIB-4 or eGFR and does not assign HIV status.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
