Identification of a DNA damage repair gene-related signature for lung squamous cell carcinoma prognosis.
Article in Thoracic cancer, 2022. 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
backgroundDNA damage repair (DDR) plays a role in the tumorigenesis and progression of lung squamous cell carcinoma (LUSC), but the predictive value of DDR in LUSC has not been fully elucidated.
methodsThe LUSC datasets were retrieved from the Cancer Genome Atlas databases. Univariate Cox regression and least absolute shrinkage and selection operator regression were integrated to identify critical genes and construct a DDR gene signature. We performed Kaplan-Meier (KM) curve to compare the overall survival (OS) between the two groups based on DDR signature and used the CIBERSORT tool to compare the immune cell composition. Further gene set enrichment analysis (GSEA) was performed on the differential expressed genes.
resultWe established the DDR-related gene signature on LUSC. KM curve showed the low-risk group had a better prognosis than the high-risk group in the training set (p = 0.022673) and the complete set (p = 0.003201). The area under receiver operating characteristic curve for OS was 0.98, 0.96, and 0.97 in the training dataset, testing dataset, and the complete dataset, respectively. The composition of immune cells was different between the high- and low-risk group. The GSEA result suggests that genes of the patients in low-risk group were mainly enriched in the DNA adducts; drug metabolism-cytochrome P450, metabolism of xenobiotics by cytochrome P450.
conclusionThis study identified DDR-associated potential biomarkers related to overall survival of LUSC and establishes the DDR-associated gene signature.
