Detection of circulating tumour cells on mRNA levels with established breast cancer cell lines.
Article in Biomedical reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Circulating tumour cells were detected and quantified by real-time polymerase chain reaction (PCR) in peripheral blood, based on the fact that the expression of certain genes is upregulated in tumour tissues in comparison to surrounding blood cells. Calibration curves showing gene expression as functions of the number of tumour cells within a blood sample were prepared. Blood samples were therefore spiked with cells of breast cancer cell lines, RNA was extracted, transcribed to complementary DNA (cDNA) and used in real-time PCR reaction on the Cytokeratins (CK) 8, 18 and 19. Calibration curves were generated by Microsoft™ Excel®. Relative quantification curves of gene expression in different breast cancer cell lines showed no unitary tendencies. The oscillations in the relative quantification curves of gene expression suggested an occurrence of immunological effects, leading to an apparent agglutination of added tumour cells together with the blood cells of the sample. Thus, strategies to obtain evaluable results should be considered.
