      "@value" : "Background The aim of the study was to assess the efficacy and safety of tofacitinib and its impacton quality of life in patients with moderate-to-severe ulcerative colitis.\nMethods We conducted a systematic review and meta-analysis of randomized controlledtrials comparing tofacitinib with placebo or any active comparator. We searched Medline,Embase, the Cochrane Library and gray literature for articles published up to May 2017.We synthesized data using a fixed-effect model. We conducted subgroup analysis based onprior exposure to anti-tumor necrosis factor (TNF). We summarized the strength of evidenceusing the Grading of Recommendations Assessment, Development and Evaluation (GRADE)approach.\nResults We included three trials with 1220 participants. Compared with placebo, tofacitinib waseffective in inducing clinical remission (odds ratio [OR] 3.84, 95% confidence interval [CI] 2.29-6.44, I2: 41%, GRADE: moderate), clinical response (OR 2.95, 95%CI 2.21-3.95, I2: 0%, GRADE:high), mucosal healing (OR 2.70, 95%CI 1.81-4.03, I2: 0%, GRADE: high). Tofacitinib was effectivein both anti-TNF-naïve and -experienced patients. Tofacitinib had a favorable effect on qualityof life. There were no significant differences in the safety profile in terms of the incidence of anyor serious adverse events compared to placebo. The risk for infections was increased (OR 1.51,95%CI 1.05-2.19, I2: 0%, GRADE: moderate), but the incidence of serious infections did not differbetween tofacitinib and placebo.\nConclusion In patients with moderate-to-severe ulcerative colitis, short-term treatment withtofacitinib is effective for induction of remission and improvement of quality of life.\nKeywords Tofacitinib, ulcerative colitis, meta-analysis\nAnn Gastroenterol 2018; 31 (5): 572-582"
