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
This study aims to develop a nomogram for predicting the overall survival (OS) of early-onset colorectal cancer with liver metastasis (EOCRC-LM) patients who underwent primary tumor resection combined with chemotherapy. Using the SEER database (2010-2015), we identified EOCRC-LM underwent primary tumor resection and chemotherapy. Eligible cases were randomly split into training/validation cohorts. Least Absolute Shrinkage and Selection Operator(LASSO) regression and multivariate Cox analysis identified independent OS predictors, which were integrated into a nomogram. Model performance was assessed via calibration curves, time-dependent Receiver Operating Characteristic, and Decision Curve Analysis (DCA), demonstrating clinical utility. A cohort of 1049 early-onset colorectal cancer patients with liver metastases underwent tumor resection and chemotherapy was analyzed using SEER data (2010-2015), randomly divided into training (n = 734) and validation (n = 315) cohorts. LASSO and multivariate Cox regression identified eight independent prognostic factors: marital status, tumor location, T/N stage, CEA level, lymph node count, and bone/lung metastases. The nomogram showed strong predictive accuracy, with training cohort Area Under the Curve(AUCs) of 0.70 (0.66, 0.73) (2-year), 0.72 (0.68, 0.76) (3-year), and 0.77 (0.72, 0.80) (5-year), and validation cohort AUCs of 0.68 (0.62, 0.74) , 0.71 (0.65, 0.77) , and 0.80 (0.75, 0.86) , respectively. Calibration curves confirmed close alignment between predicted and observed survival, while DCA validated clinical utility for personalized risk assessment. The clinical prediction model developed from SEER data for OS in EOCRC-LM patients underwent combined primary tumor resection and chemotherapy demonstrated robust performance in prognostic evaluation. This nomogram-based tool provides clinicians with reliable quantitative guidance and a theoretical foundation for implementing personalized therapeutic strategies, thereby addressing the critical need for precision medicine in this clinically heterogeneous population.
