Primary Outcome Measures

Age at the Time of Diagnosis	At diagnosis (anytime between Jan 2010 and Dec-2021, approximately 12 years (from data collected and analyzed retrospectively over 5 months)	Participant's age at the time of ulcerative colitis diagnosis was presented in this outcome measure. Index was considered as date of initiation of tofacitinib treatment for ulcerative colitis.
Duration of Ulcerative Colitis	At index (from data collected and analyzed retrospectively over 5 months)	Duration of ulcerative colitis was presented in this outcome measure. Index was considered as date of initiation of tofacitinib treatment for ulcerative colitis.
Number of Participants With Extent of Colonic Involvement According to the Montreal Classification	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.
Mayo Score at Initiation of Tofacitinib	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.
Partial Mayo Score at Initiation of Tofacitinib	At index (from data collected and analyzed retrospectively over 5 months)	Partial Mayo score consisted of 3 components: rectal bleeding, stool frequency, and physician (doctors) assessment of disease activity. 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. Index was considered as date of initiation of tofacitinib treatment for ulcerative colitis. Partial Mayo scores and sub-scores have been collected by doctors independently as part of standard of care.
Number of Participants According to Endoscopic Findings Based on Histology	At index (from data collected and analyzed retrospectively over 5 months)	Endoscopic findings were graded from 0 to 3 where 0 = Normal or inactive disease (Normal vascular pattern with arborization of capillaries clearly defined, or with blurring or patchy loss of capillary margins), 1 = Mild disease (erythema, decreased vascular pattern, mild friability), 2 = Moderate disease (marked erythema, absent vascular pattern, friability, erosions), 3 = Severe disease (spontaneous bleeding, ulceration). Index was considered as date of initiation of tofacitinib treatment for ulcerative colitis.
Number of Participants According to Endoscopic Sub Score Based on Mayo Score	At index (from data collected and analyzed retrospectively over 5 months)	Endoscopic findings were graded from 0 to 3 where 0 = Normal or inactive disease, 1 = Mild disease (erythema, decreased vascular pattern, mild friability), 1 = Mild disease (erythema, decreased vascular pattern, mild friability), 3 = Severe disease (spontaneous bleeding, ulceration). Mayo score was composed of four components: rectal bleeding, stool frequency, physician assessment of disease activity and endoscopy findings.
