1 · What the graph read from 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.

2 · The registry

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

Cancer metastasis occurs due to the ability of the tumour to evade immune recognition and response by altering the major histocompatibility complex class I (MHC class I). A comprehensive understanding of the MHC class I alteration in breast cancer metastasis is vital for the rational design and improvement of immunotherapies for advanced cancer. In this study, we associate it with the elevation of 'neonatal' Nav1.5 (nNav1.5) mRNA expression in the aggressive type of human breast cancer cells. Using real-time PCR, lower expression of TAP1 (by - 4.83-fold), which is a part of the MHC class I antigen processing machinery (APM) pathway component, in contrast to the greater expression of nNav1.5 (by 3.76-fold), along with other metastatic markers, MMP1 (by 57.48-fold) and fibronectin (by 2.88-fold) in aggressive human breast cancer cell line, MDA-MB231 were obtained. Subsequent knockdown of nNav1.5 (by 52.6%) in MDA-MB-231 via siRNA-
