Total malignancy excluding non-melanoma skin cancer included lymphoma, lung cancer, breast cancer, skin cancer (melanoma), and other cancers. Mean of incidence rate of total malignancy excluding non-melanoma skin cancer was calculated and reported.

Mean Change From Baseline in Clinical Disease Activity Index (CDAI) at 6 Months

时间窗: Baseline, Month 6 (Retrospective data collection from 01 March-2016 to 30-Jun-2022)

CDAI was the numerical sum of four outcome parameters: Tender joint count (TJC) or swollen joint count (SJC) both based on a 28-joint assessment, participant's assessment (PtGA) of disease activity and physician's global assessment (PGA) of disease activity both assessed on a 0 to 10 centimeter (cm) visual analogue scale (VAS) (higher scores indicated greater affection due to disease activity). CDAI total score ranged from 0 to 76. Higher scores indicated greater affection due to disease activity. CDAI less than or equal to (\<=) 2.8 indicated disease remission, greater than (\>) 2.8 to 10 indicated low disease activity, \>10 to 22 indicates moderate disease activity, and \>22 indicated high disease activity. Mean change from baseline was calculated by subtracting the baseline value from the 6-month value.

Mean Change From Baseline in Japanese Health Assessment Questionnaire (J-HAQ) at 6 Months

HAQ: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom, arise, eat, walk, reach, grip, hygiene, and common activities over past week. Each item scored on 4-point scale, 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as sum of domain scores and divided by number of domains answered. Total possible score range 0-3: 0=least difficulty and 3=extreme difficulty. Higher scores indicated worse functioning. Mean change from baseline was calculated by subtracting the baseline value from the 6-month value.

Mean Change From Baseline in Participant's Pain at 6 Months

时间窗: Baseline, Month 6 (Retrospective data collection from 01 March-2016 to 30-Jun-2022)

Participants were asked the following question to answer on a numeric rating scale (NRS): "How much pain have you had because of your arthritis in the past week?" The scale ranged from 0-100, where 0=no pain and 100=pain as bad as it could be. Higher scores indicated worsening of condition. Mean change from baseline in participant's pain was calculated and reported.

Mean Change From Baseline in Morning Stiffness at 6 Months

时间窗: Baseline, Month 6 (Retrospective data collection from 01 March-2016 to 30-Jun-2022)

CDAI and other continuous measures like morning stiffness were represented as mean change from baseline to 6-months and were calculated by subtracting the baseline value from the 6-month value.

Change in Percentage of Participants Reporting Moderate/Severe/Extreme Difficulty Levels for EQ-5D-5L From Baseline at Month 6

时间窗: Baseline, Month 6 (Retrospective data collection from 01 March-2016 to 30-Jun-2022)

EQ-5D-5L was a participant rated questionnaire to assess health-related quality of life. It assessed level of current health in 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression. Each domain had 5 levels: 1= no problems, 2=slight problems, 3=moderate problems, 4=severe problems, or 5=extreme problems/unable to do task. Total score for each domain was from 1-5, where higher levels/scores indicated more difficulty in each domain.

CDAI: numerical sum of 4 outcome parameters: TJC and SJC based on a 28-joint assessment, PtGA and PGA assessed on 0-10 cm VAS; CDAI total score = 0-76, higher scores=greater affection due to disease activity (DA). CDAI \<= 2.8 indicates disease remission, \> 2.8 to 10 = low DA, \>10 to 22 = moderate DA, and \>22 = high DA. MCID improvement defined by difference in CDAI from baseline (at time of tofacitinib initiation) to 6-month visit.
