Clinical Significance and Potential Molecular Mechanisms of Angiotensin-Converting Enzyme 2 in Colorectal Cancer.
Article in World journal of oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Angiotensin-converting enzyme 2 (ACE2) exhibits tumor-suppressive potential in cancers, but its role in colorectal cancer (CRC) is unclear. The aim of the study was to investigate ACE2 expression, clinical significance, and immune microenvironment associations in CRC. Methods: A multidimensional approach was taken using single-cell RNA sequencing and spatial transcriptomics to analyze ACE2 expression in CRC cells. High-throughput data from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) (2,275 CRC and 1,269 adjacent tissues) were used to assess mRNA levels. Immunohistochemistry was performed to examine ACE2 protein expression in 66 CRC and 75 adjacent tissues. Molecular testing assessed associations with Kirsten rat sarcoma viral oncogene homolog ( Results: ACE2 was highly expressed in malignant cells and Ki-67-activated regions. mRNA and protein levels were upregulated in CRC (standardized mean difference (SMD) = 0.321, area under the curve (AUC) = 0.844). High ACE2 exhibited significant associations with nerve invasion, lower expression in mucinous adenocarcinomas, and Conclusions: The upregulation of ACE2 is associated with nerve invasion, pathological type, and an immunosuppressive microenvironment with reduced CD8
