Proteomics score: a potential biomarker for the prediction of prognosis in non-small cell lung cancer.
Article in Translational cancer research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBiomarkers based on quantitative genomics features are related to clinical prognosis in various cancer types. However, the association between proteomics and prognosis in non-small cell lung cancer (NSCLC) is unclear. Here, we developed a proteomics score for the prediction of prognosis in patients with NSCLC undergoing partial pneumonectomy.
methodsIn total, 693 patients with NSCLC with reverse-phase protein array data from The Cancer Genome Atlas were randomly divided into discovery (n=346) and validation (n=347) cohorts. The least absolute shrinkage and selection operator algorithm (LASSO) was used to select the optimal features and build a proteomics score in the discovery set. Additionally, the performance of the proteomics nomogram was estimated using its calibration and time-dependent receiver operator characteristic (ROC) curves. Selection genomics were analyzed via bioinformation.
resultsUsing the LASSO model, we established a novel classifier based on 15 features. The proteomics score was significantly associated with overall survival (OS; both P<0.0001) and disease-free survival (DFS; both P<0.0001) in the discovery and validation cohorts. Additionally, the proteomics nomogram showed good discrimination calibration and precise prediction in the two cohorts. Bioinformation revealed that the selection genomics were enriched in negative regulation of immune system processes using gene ontology (GO) and pathways in cancer with the Kyoto Encyclopedia of Genes and Genomes (KEGG).
conclusionsThe proposed proteomics score and nomogram showed excellent performance for the estimation of OS and DFS, which may help clinicians better identify patients with NSCLC who can benefit from surgery.
