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
purposeTo identify risk factors for febrile neutropenia (FN) in patients with esophageal cancer receiving the first cycle of definitive chemoradiotherapy with 5-fluorouracil plus cisplatin and concurrent radiotherapy (FP+R therapy).
methodsWe conducted a retrospective single-center cohort study of patients who started FP+R at Oita University Hospital between April 2011 and June 2023. The primary outcome was FN onset in cycle 1. Univariate tests and multivariable logistic regression [forced entry: age, C-reactive protein (CRP), prognostic nutritional index (PNI), dysphagia] were used to evaluate association with FN development. Receiver operating characteristic (ROC) analysis was conducted to evaluate the predictive performance of baseline CRP for FN.
resultsAmong 120 patients studied, grade ≥ 3 neutropenia occurred in 37 (30.8%) and FN in 14 (11.7%) during the first cycle. In multivariable analysis, higher baseline CRP was independently associated with increased FN risk [odds ratio (OR) 1.790; 95% confidence interval (CI) 1.120-2.850; p = 0.014], whereas dysphagia showed a non-significant association (OR 2.890; p = 0.145). Age and PNI were not independent predictors. ROC analysis for baseline CRP yielded area under the ROC curve of 0.699 (95% CI 0.520-0.877; p = 0.021) with optimal cut-off value of 0.68 mg/dL (sensitivity 61.54%; specificity 70.65%).
conclusionBaseline systemic inflammation, indicated by elevated CRP, is an independent risk factor for FN development during FP+R therapy. Despite the regimen having an intermediate FN risk, patients with elevated pre-treatment CRP may need closer monitoring. This biomarker may help clinicians perform a more comprehensive risk assessment alongside conventional patient-specific factors.
