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

backgroundMicroRNAs (miRNAs) may function as suppressors or promoters of tumor metastasis according to their messenger RNA targets. Previous studies have suggested that miR-9 and miR-151-5p are associated with metastasis in breast cancer and hepatocellular carcinoma, respectively. We aimed to further establish the potential roles of miR-9 and miR-151-5p in tumor invasion and metastasis and investigate their use as biomarkers.

methodsWe used quantitative real-time PCR (qRT-PCR) to measure differences in miR-9 and miR-151-5p expression between primary breast tumors and their lymph-node metastases in 194 paired tumor samples from 97 patients. We also correlated expression levels with histologic data to investigate their utility as biomarkers.

resultsThere were no significant differences in miR-9 expression between the primary tumors and lymph nodes; however, miR-151-5p expression was significantly lower in the lymph-node metastases than in their corresponding tumors (p < 0.05). miR-9 levels were elevated in primary breast tumors from patients diagnosed with higher-grade tumors (p < 0.05); however, no differences were observed in miR-151-5p levels between different grades of tumor. Interestingly, miR-9 levels were elevated in invasive lobular carcinomas (ILC) compared with invasive ductal carcinomas (IDC; p < 0.01).

conclusionsIn aggregate, these data suggest that miR-151-5p upregulation may suppress metastasis in primary breast tumors. Both miRNAs may serve as useful biomarkers in future clinical trials in breast cancer.
