Number of Participants With Extent of Colonic Involvement According to the Montreal Classification
Time Frame: At index (from data collected and analyzed retrospectively over 5 months)
Montreal classification was used to classify UC based on extent of inflammation. Three subgroups of UC were: E1= ulcerative proctitis: involvement limited to rectum i.e, proximal extent of inflammation is distal to rectosigmoid junction, E2= left sided, distal colitis: involvement limited to portion of colorectum distal to splenic flexure and E3= extensive UC (pancolitis): involvement extends proximal to the splenic flexure. Index was considered as date of initiation of tofacitinib treatment for UC.
At index (from data collected and analyzed retrospectively over 5 months)
Mayo Score at Initiation of Tofacitinib
Time Frame: At index (from data collected and analyzed retrospectively over 5 months)
Mayo score was composed of four components: rectal bleeding, stool frequency, physician (doctors) assessment of disease activity, and endoscopy findings. Each sub score ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe). These sub scores were summed up to give a total score range of 0 to 12, where higher scores indicated higher disease severity. Index was considered as date of initiation of tofacitinib treatment for ulcerative colitis. Mayo scores and sub-scores have been collected by doctors independently as part of standard of care.
At index (from data collected and analyzed retrospectively over 5 months)

Each sub score ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe). These sub scores were summed up to give a total score range of 0 to 9, where higher scores indicated higher disease severity.

Clinical remission in participants was defined as a full Mayo score of <=2 points, with no individual sub score exceeding 1 point with rectal bleeding sub-score of 0. Full Mayo score consisted of 4 sub scores: rectal bleeding, stool frequency, physician assessment of disease activity, and endoscopy findings, each graded from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe). These sub scores were summed up to give a total score range of 0 to 12, where higher scores indicated higher disease severity. Steroid-free clinical remission was defined as participants who were treated with corticosteroids at baseline and did not require any corticosteroid treatment during the period >=4 weeks prior to the visit.

These sub scores were summed up to give a total score range of 0 to 9, where higher scores indicated higher disease severity. Steroid-free clinical remission was defined for participants who were treated with corticosteroids at baseline and did not require any corticosteroid treatment during the period >=4 weeks prior to the visit.
