NOS2 as a prognostic biomarker for early-onset colorectal cancer based on public data and clinical validation analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
Early-onset colorectal cancer (EOCRC) was characterized by strong aggressiveness and high malignancy. The aim of this study was to screen suitable biomarkers for patients with EOCRC. EOCRC from The Cancer Genome Atlas Program (TCGA) database and Gene Expression Mapping (GEO) database were used to screen biomarkers for prognosis and treatment guidance. Clinical samples were used to verify the expression situation of these candidate biomarkers. The results showed the immune-related gene nitric oxide synthase 2 (NOS2) was independently associated with the poor prognosis of EOCRC patients in both TGCA and GEO database. The Immune Dysfunction and Exclusion (TIDE) analysis showed that multiple immunotherapy signatures, such as TIDE, Exclusion, and CAF, were difference among EOCRC patients with different risk scores, and significantly correlated with the expression of NOS2. Sensitivity analysis of chemotherapy drugs showed that NOS2 was significantly correlated with several chemotherapy drugs, such as MG.132_1862, BMS.754807_2171, and GEN.317_1926. Clinical validation analysis showed that the expression of NOS2 and its related genes CXCL1 and CXCL2 were significantly decreased in EOCRC patients. The results suggested that NOS2 can be used as a potential biomarker for EOCRC, which can be used for prognosis and guidance of immunotherapy and chemotherapy.
