In this article, the Disease Activity Index for Psoriatic Arthritis (DAPSA) disease states were calculated incorrectly across all treatment arms and timepoints, resulting in patients being wrongly allocated to a worse DAPSA disease state.
This error impacted three rows in Table 2. The corrected rows from Table 2 are provided below.
