Predictors of histologic remission in patients with biologic-naïve, moderate-to-severe ulcerative colitis treated with first-line biologic agents and small-molecule drugs: a single-center, retrospective cohort study.
Article in Intestinal research, 2024. 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
BACKGROUND/
aimsThe prevalence and incidence of ulcerative colitis (UC) in Korea is increasing. Each patient has a different disease course and treatment response. Recently, with the development of biologic agents, histological remission has become a treatment goal. In this study, we aimed to identify the predictors of histological remission after first-line biologic agent treatment in patients with biologic agent-naïve UC.
methodsWe retrospectively analyzed the medical records of 92 patients who had been diagnosed with UC and treated with first-line biologic agent treatment at our center, between 2015 and 2022. The clinical characteristics, laboratory test results, and endoscopic and biopsy findings were analyzed. Histological remission was defined as the absence of cryptitis, crypt abscesses, and inflammatory cells on histology. Univariate and multivariate logistic regression analyses were performed to identify the predictors of histological remission after first-line treatment.
resultsOf the total 92 patients, 25 (27.2%) achieved histological remission. Each cohort had a varied body mass index (BMI) distribution, with a statistically significant overweight ratio, as defined by the Asian-Pacific BMI category of 23-25 kg/m2, of 48.0% in the histological remission cohort (P= 0.026). A causal correlation between the overweight category and histological remission was confirmed (odds ratio, 3.883; 95% confidence interval, 1.141-13.212; P= 0.030).
conclusionsWe confirmed that the overweight category was a predictor of histological remission after first-line treatment with a biological agent. However, as BMI does not account for skeletal muscle mass, future studies are required to confirm the correlation between skeletal muscle mass and histological remission.
