Neutrophil-to-Lymphocyte Ratio at Diagnosis Predicts Colonoscopic Activity in Pediatric Inflammatory Bowel Diseases.

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
introductionNeutrophil-to-lymphocyte ratio (NLR) is a novel biomarker studied in several autoimmune diseases including inflammatory bowel disease (IBD) in adults but poorly characterized in pediatric IBD (pIBD). We aimed to primarily investigate the relationship between NLR and pIBD endoscopic disease severity. We also examined whether NLR predicted hospitalization, surgery, and therapy response by 52 weeks.
methodsWe used the Canadian Children IBD Network prospective inception cohort including patients < 18 years old with baseline data from 2013 to 2022. We excluded patients with concurrent diseases affecting NLR. Both Mayo endoscopic score (MES) and simple endoscopic scale for Crohn's disease (SES-CD) were dichotomized as low activity (quiescent-mild) and high activity (moderate-severe). For therapy responses, we examined year-1 steroid- and biologic-free remission. We used logistic regression for binary outcomes.
resultsA total of 580 patients with ulcerative colitis and 1,081 patients with CD were included. High NLR was associated with high-activity MES and SES-CD in both univariate and multivariable analyses (odds ratio = 1.45, 95% CI = 1.07-1.97, P value = 0.016; and odds ratio = 1.42, 95% CI = 1.04-1.94, P value = 0.026, respectively). We also calculated the best NLR cutoff point to predict MES (1.90, sensitivity = 68%, specificity = 67%, area under the curve [AUC] = 0.67, AUC 95% CI = 0.59-0.74) and SES-CD (2.50, sensitivity = 63%, specificity = 69%, AUC = 0.66, AUC 95% CI = 0.59-0.75) high activity. NLR did not predict therapy response in either ulcerative colitis or CD. DISCUSSION: Patients with pIBD with high baseline NLR are more probable to have worse endoscopic disease at diagnosis. This highlights NLR potential as a reliable noninvasive biomarker of disease activity. The predictive power of NLR is based mostly on neutrophils and the balance between neutrophils and lymphocytes.
