The Physician Global Assessment (PGA) as recommended by the PGA International Standardisation COnsensus in SLE consortium. (A) The PGA graph, consisting of a 0–3 visual analogue scale (VAS) with anchored values. (B) The correct way to score the PGA, by putting a vertical tick on the 0–3 VAS as a continuous measure with one decimal (eg, 1.4 on a 0–3 scale). The PGA scale ranges from 0=‘no disease activity’ to 3=‘most severe disease activity’. Values ≥0.5 but ≤1 refer to mild disease activity; values >1 but ≤2 refer to moderate disease activity and values >2 up to 3 refer to severe disease activity. The PGA should be scored by experienced physicians, preferably by the same rater at each visit.
