1 · What the graph read from it

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.

2 · The registry

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

purposeColorectal cancer is a leading cause of cancer-associated death. Metastatic disease in the liver is common and is associated with severely diminished survival rates. Despite various treatment modalities, comprehensive long-term survival data following surgical interventions for colorectal liver metastases (CRLM) is limited.

methodsThis nationwide multicenter study used data from the Danish Liver Cancer Group registry. Patients undergoing initial surgery, including hepatic resection, ablation, or both, were included. Survival analysis was conducted using the Kaplan-Meier estimator and Cox proportional hazards models to evaluate the prognostic impact of clinical preoperative factors. Multiple imputation was performed for missing values.

resultsAmong 2316 patients, median survival was four years, with 1-, 3-, 5-, and 7-year survival rates of 91%, 61%, 42%, and 32%, respectively. Advancing age per year, higher performance status, metastases exceeding 3 cm, and an increasing number of metastases significantly increased mortality risks. Multivariable analysis further refined the hazard ratios (HR) for age per year (HR 1.02), WHO performance status ≥ 2 (HR 1.50), diameter of largest metastasis in cm (HR 1.19) and number of metastases ≥ 3 (HR 1.51).

conclusionThis study highlights the importance of considering age, performance status, and tumor burden in the preoperative evaluation to improve clinical outcomes.
