Impact of Therapeutic Agents on Serum Leucine-Rich Alpha-2 Glycoprotein for Monitoring Endoscopically Remitted Ulcerative Colitis.

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
introductionSerum leucine-rich alpha-2 glycoprotein (LRG) levels are measured to monitor ulcerative colitis; however, the impact of concomitant medications on LRG remains unclear. This exploratory study aimed to determine the effects of various agents on serum LRG levels.
methodsWe conducted a single-center, retrospective study using medical records at our hospital from October 1, 2020, to June 30, 2023. Patients who underwent lower gastrointestinal endoscopy within 1 year before or after LRG measurement and had confirmed mucosal healing were included. The effects of medication on LRG levels were assessed using multiple regression analysis following multiple imputations. The analyzed agents included 5-aminosalicylic acid (5-ASA), immunomodulators, corticosteroids, calcineurin inhibitors, Janus kinase inhibitors, vedolizumab, interleukin-23 receptor antagonists, and anti-tumor necrosis factor (TNF)-α agents.
resultsA total of 214 patients (351 measurements) were included. The median LRG was 11.2 μg/mL. Among patients, 63.2 had a Mayo Endoscopic Subscore of 0, while 36.8% had a score of 1. The frequency of medication use was as follows: 5-ASA (88.9%), immunomodulators (13.1%), corticosteroids (2.6%), calcineurin inhibitors (0.9%), Janus kinase inhibitors (5.7%), vedolizumab (3.4%), interleukin-23 receptor antagonists (1.7%), and anti-TNF-α agents (7.4%). Corticosteroids, calcineurin inhibitors, Janus kinase inhibitors, and anti-TNF-α agents were negatively associated with LRG (β = -3.42, -10.4, -2.34, and -3.01, respectively). Conversely, vedolizumab and interleukin-23 receptor antagonists were positively associated with LRG (β = 1.83 and 4.69, respectively). DISCUSSION/
conclusionLRG levels are influenced by medications, even in patients with mucosal healing. These effects should be considered when using LRG to monitor UC.
