Prognostic value of expression levels of miR-148a, miR-152 and HLA-G in colon cancer.
Article in Oncology letters, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Aberrant expression of human leukocyte antigen G (HLA-G), an immunosuppressive molecule, has been observed in various cancer types. The exact mechanism of HLA-G expression is unclear. HLA-G expression is associated with low expression levels of microRNA (miR)-148a and miR-152. To the best of our knowledge, the prognostic value of the expression levels of miR-148a, miR-152 and HLA-G has not been investigated in colon cancer. The aim of the present study was to investigate the relationship between the presence of HLA-G molecules and the expression levels of miR-148 and miR-152 in colon cancer. In addition, the association of both HLA-G and miR expression with survival results and clinicopathological data was determined. An immunohistochemical method was used for detection of HLA-G expression in the tumor tissues and adjacent healthy tissues of 108 patients with colon cancer. Reverse transcription-quantitative PCR was used for miR analysis. HLA-G was expressed in 82 (75.9%) of the cancer samples, and there was no staining in normal tissues. HLA-G expression >20%, which was found in 41.7% (45/108) of the patients with colon cancer, was significantly positively associated with patient survival (P=0.039). Additionally, miR-148a levels were lower in the tumor tissues compared with the adjacent healthy tissues. No differences were found for miR-152 expression. In addition, mir-148a levels were found to be significantly lower (P=0.001) in HLA-G-positive tumor tissues than HLA-G-negative tumor tissues, but no such relationship was found for miR-152 levels. The presence of HLA-G expression was associated with poor survival outcomes. HLA-G is one of the prognostic factors in colon cancer, and decreased miR-148a expression in colon cancer tissues may be associated with HLA-G-mediated carcinogenesis.
