Post-marketing surveillance of tofacitinib in patients with ulcerative colitis in Japan: a post hoc analysis of safety and effectiveness in older (≥65 years) and younger (<65 years) patients.
Article in Intestinal research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
aimsTo assess, post hoc, tofacitinib safety/effectiveness in patients with ulcerative colitis (UC), stratified by age, using data from a 60-week post-marketing surveillance (PMS) study in Japan.
methodsAll patients with UC receiving tofacitinib in Japan were enrolled in a large PMS study. Incidence proportions of adverse events (AEs), incidence rates (IRs; unique patients with events/100 patient-years of exposure) of clinically important AEs, reasons for discontinuation, and partial Mayo score clinical remission, stratified by age ( ≥ 65 and < 65 years), were evaluated.
resultsThe analysis included 212 older ( ≥ 65 years) and 1,770 younger ( < 65 years) patients. Demographics and baseline disease characteristics were generally similar between groups; however, more older versus younger patients had cardiovascular disease (23.1% vs. 4.6%). Incidence proportions of AEs were comparable between groups, but IRs (95% confidence intervals) in older versus younger patients were numerically higher for herpes zoster (9.81 [5.72-15.71] vs. 5.44 [4.28-6.82]), and higher for serious infections (4.45 [1.92-8.76] vs. 1.14 [0.65-1.85]). More older versus younger patients discontinued due to AEs (28.6% vs. 17.6%); more younger versus older patients discontinued due to insufficient clinical responses (50.3% vs. 35.2%). Clinical remission rates through 60 weeks were generally similar between groups.
conclusionsOlder patients had higher IRs of herpes zoster and serious infection than younger patients, although tofacitinib effectiveness was similar between age groups. Discontinuation due to AEs was more common in older patients. Despite the smaller sample size of older versus younger patients, a focused evaluation of older patients is of benefit.
