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
backgroundThe effectiveness of neoadjuvant chemotherapy (NAC) for individuals with early-stage hepatocellular carcinoma (HCC) is still a subject of controversy and uncertainty. This study sought to create a risk categorization model using a nomogram to pinpoint patients with early-stage HCC that might derive benefits from NAC.
methodsThis retrospective cohort study was based on data from the SEER Research Plus database (April 2021 release), covering the years 2006 to 2018. The definition of NAC was chemotherapy performed prior to surgery, while that of no NAC (No-NAC) was surgery without chemotherapy before the operation. We implemented stepwise Cox regression to discover prognostic factors and utilized these factors to develop a nomogram for forecasting the 3-, 5-, and 10-year cancer-specific survival (CSS) for patients with early-stage HCC. We utilized receiver operating characteristic curves, calibration curves, and decision curve analysis to evaluate the prognostic capacity of the nomogram. Finally, prognostic stratification was performed based on the optimal boundary value of the nomogram score, and we utilized the Kaplan-Meier method to analyze the survival rate.
resultsA sum of 11,721 HCC patients was incorporated in the analysis. After adjustment through propensity score matching, the baseline characteristics of the NAC and No-NAC groups were not statistically different. A total of 4030 patients, with the clinical data of their marital status, tumor number, fibrosis, alpha fetoprotein, grade, age, T stage, tumor size, race, and surgical approach (i.e., 11 variables) were employed in the building of the nomogram. The constructed nomogram exhibited good discriminatory ability and accuracy in predicting CSS in patients with early-stage HCC. Based on the nomogram, individuals can be classified into three distinct risk categories. In the group identified as high-risk, the CSS of the patients was significantly enhanced by NAC.
conclusionsThis study developed and validated a nomogram for predicting 3-, 5-, and 10-year CSS in early-stage HCC patients, incorporating demographic and clinical factors. Risk stratification identified high-risk patients who benefited significantly from NAC. These findings support personalized treatment decisions, though external validation is needed.
