Development and validation of pretreatment nomogram for disease-specific mortality in gastric cancer-A competing risk analysis.
Article in Cancer medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundIn several reports, gastric cancer nomograms for predicting overall or disease-specific survival have been described. The American Joint Committee on Cancer (AJCC) introduced the attractiveness of disease-specific mortality (DSM) as an endpoint of risk model. This study aimed to develop the first pretreatment gastric cancer nomogram for predicting DSM that considers competing risks (CRs).
methodsThe prediction model was developed using data for 5231 gastric cancer patients. Fifteen prognosticators, which were registered at diagnosis, were evaluated. The nomogram for DSM was created as visualizations of the multivariable Fine and Gray regression model. An independent cohort for external validation consisted of 389 gastric cancer patients from a different institution. The performance of the model was assessed by discrimination (Harrell's concordance (C)-index), calibration, and decision curve analysis. DSM and CRs were evaluated, paying special attention to host-related factors such as age and Eastern Cooperative Oncology Group performance status (ECOG PS), by using Gray's univariable method.
resultsFourteen prognostic factors were selected to develop the nomogram. The new nomogram for DSM exhibited good discrimination. Its C-index of 0.887 surpassed that of the American Joint Committee on Cancer (AJCC) clinical staging (0.794). The C-index was 0.713 (AJCC, 0.582) for the external validation cohort. The nomogram showed good performance internally and externally, in the calibration and decision curve analysis. Host-related factors including age and ECOG PS, were strongly correlated with competing risks.
conclusionsThe newly developed nomogram accurately predicts DSM, which can be used for patient counseling in clinical practice.
