The penultimate sentence under the heading Methods in Abstract section should have read “Cost per ASAS40 responder (CPR) was calculated as the 16-week treatment costs divided by ASAS40 response rates.”

The last sentence under the heading Costs in Methods section should have read “The dosing schedules and unit and administration costs were used to calculate the costs for 16-week treatment for each therapy.”

The second sentence in third paragraph under the heading Statistical Methods in Methods section should have read “CPR was calculated as the 16-week treatment costs for each advanced therapy divided by NMA-estimated ASAS40 absolute response rates.”

The header “Cost Per Responder Over 12 Weeks” under Results section should have read “Cost Per Responder Over 16 Weeks.”

Figure 4 caption should have read “Cost per responder for ASAS40 over 16 weeks in bio-naïve (a) and bio-IR (b) patients with AS…”

In the Supplementary PDF for this article, the Supplementary Fig. 4 title should have read “Supplementary Fig. 4: Cost per responder for ASAS40 over 16 weeks among TNF-IR patients.”
