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
introductionCardiotoxicity has become a major concern in cancer patients, especially those with lung cancer, as anti-tumor therapies can significantly affect patient survival and quality of life. This study aims to develop and validate a dynamic nomogram based on the Inflammation Burden Index (IBI) to predict the risk of cardiac injury within one year after anti-tumor treatment in lung cancer patients.
methodsThis single-center, retrospective study included 1386 lung cancer patients who underwent myocardial enzyme testing between July 2018 and January 2023. The IBI was calculated as: IBI = (CRP (mg/dL) × Neutrophils (/μL)) / Lymphocytes (/μL). Statistical analysis using SPSS 22.0 and R 4.4.1, including machine learning algorithms and multivariate logistic analysis, identified independent predictors of cardiac injury. An online dynamic nomogram was developed and validated using internal validation, ROC curves, and decision curve analysis (DCA).
resultsThe average age of the 1386 patients was 61.98 ± 9.22 years. Significant independent predictors included age, BMI, hypertension, immunotherapy, D-dimer, LDH, NSE, CKMB, and IBI. The nomogram showed strong discriminative ability with AUC-ROC values of 0.85 for the training set and 0.86 for the validation set. Calibration curves confirmed good fit, and DCA showed high clinical utility.
conclusionAn online dynamic nomogram based on clinical and inflammatory markers was developed to predict cardiac injury in lung cancer patients following anti-tumor therapy. The model shows strong discriminative ability and potential clinical value, which can provide vital information for oncologists when designing customized clinical treatments.
