Tacrolimus as rescue therapy for steroid-dependent/steroid-refractory ulcerative colitis: Experience from tertiary referral center in India.
Article in Indian journal of gastroenterology : official journal of the Indian Society of Gastroenterology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionBetween 20% and 40% of patients with severe ulcerative colitis (UC) are either steroid-refractory UC (SRUC) or steroid-dependent UC (SDUC). Tacrolimus is an oral and relatively inexpensive drug, which has been extensively used in Japan for steroid-refractory and steroid-dependent disease.
methodsPatients diagnosed with SDUC/SRUC were treated with tacrolimus 0.05-0.1 mg/kg in this prospective study. Clinical Mayo score (CMS) and UC Endoscopic Index of Severity (UCEIS) were evaluated prior to starting the drug and subsequently after 8 weeks. 5-Aminosalicylic acid agents (5-ASA) and immunomodulators were continued if the patients were previously on these drugs. Clinical response at 8 weeks was defined as decrease in CMS by at least 3 points. Clinical remission was defined as CMS ≤2 and combined remission as CMS≤2 with UCEIS <3.
resultsFifty-two patients (29 males) with a mean age of 35.1± 12.8 years with predominantly E3 disease (71%) were prospectively evaluated in this study. SDUC and SRUC were diagnosed in 31 and 21 patients, respectively. Seven failed treatment within 8 weeks, four were subjected to surgery, and 3 were switched to infliximab. Forty-two patients continued tacrolimus for 8 weeks. Mean CMS and UCEIS prior to starting tacrolimus were 6 ± 1.1 and 4.8 ± 1.1, respectively. At 8 weeks, median CMS and UCEIS decreased to 2.6 ± 1.7 and 2.7 ± 1.3, respectively. Clinical response was documented in 29 patients (56%) at week 8 whereas clinical remission was seen in 25 patients (48%). Combined clinical and endoscopic remissions were seen in 18 patients (35%). Except for a single patient who developed reversible renal dysfunction, no other adverse event was observed.
conclusionOur results show that tacrolimus is effective in inducing a clinical response in 56% of patients with SDUC and SRUC. In view of its low cost and safety profile, it may be considered first-line therapy for SDUC/SRUC.
