The RA NarRAtive Weighted Survey Methodology
The RA NarRAtive Patient Survey
The RA NaRAtive patient survey was conducted online by Harris Poll on behalf of Pfizer between September 4 and December 24, 2014, January 9 and 13, 2015 and September 3,2015 and January 13, 2016 among 3987 adults ages 18+ who have been diagnosed with rheumatoid arthritis (RA) in Argentina (n=217), Australia (n=481), Brazil (n=324), Canada (n=237), France (n=122), Germany (n=525), Hong Kong (n=192), Italy (n=204), Japan (n=354), South Korea (n=224), Spain (n=122), Taiwan (n=90), Turkey (n=123), the UK (n=246), and the US (n =526).2
Raw data were weighted where necessary to reflect the general adult (or online adult) population in each country (sample sizes noted above). For the global, 15-country total, a post-weight was applied to adjust for the relative size of each country's adult population within the total adult population across all countries surveyed. The unweighted sample sizes above reflect the total number of patients who completed the survey in each country, while all reported percentages are calculated based on the weighted global total described here.
Results from the RA NarRAtive patient sample survey may not reflect the experiences of the broader RA population. Raw data were not weighted at the individual country level, and are therefore only representative of the individuals who completed the survey.

The RA NarRAtive Physician Survey
The RA NarRAtive physician survey was conducted online by Harris Poll on behalf of Pfizer between August 14 and October 2, 2015 among 1666 rheumatologists ages 18+ who have seen at least five (5) RA patients in the past month whose RA is moderately to severely active or severely active in Argentina (n=130), Australia (n=60), Brazil (n=150), Canada (n=50), France (n=149), Germany (n=150), Hong Kong (n=30), Italy (n=100),Japan (n=139), South Korea (n=100), Spain (n=100), Turkey (n=SO), Taiwan (n=100), the UK (n=150), and the US (n=20 8).3
Physician results in the US were weighted by region and years in practice by gender. In all other countries, raw data were not weighted at the individual country level (sample sizes noted above), and therefore are only representative of the individuals who completed the survey. For the global, 15-country total, a post-weight was applied to adjust for the relative size of each country's adult population within the total adult population across all countries surveyed. The unweighted sample sizes above reflect the total number of HCPs who completed the survey in each country, while all reported percentages are calculated based on the weighted global total described here.

Raw data were not weighted at the individual country level, and are therefore only representative of the individuals who completed the survey.
Where permitted, some members of the Global RA NarRAtive Advisory Panel were paid honoraria for their participation. Pfizer provided travel and accommodation, as well as a compensation, to Advisory Panel members who represent patient advocacy organizations for time spent developing the survey and attending meetings to review the survey findings.
