Investigation of miR221 and miR222 as Biomarkers in Non-small Cell Lung Cancer.

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/
aimMicroRNAs (miRNA) are a class of small non-coding RNAs of 18-25 nucleotides, which regulate gene expression at the post-transcriptional level by disrupting or blocking translation of messenger RNA targets. Non-small cell lung cancer (NSCLC) represents approximately 85% of all lung cancers. Early and accurate diagnosis of the disease affects the probability of success of treatment. The purpose of this study was to investigate the expression levels of serum specific miRNA221 and miRNA222 as a biomarker in NSCLC. MATERIALS AND
methodsThirty-two NSCLC cases and 30 healthy control cases that were diagnosed at Istanbul Yedikule Chest Diseases and Thoracic Surgery Training Hospital were included in this study. miRNAs were detected using miRNA-specific quantitative real-time-PCR. The relative expression of miRNAs was calculated using the 2
resultsmiR221 and miR222 showed 1.46 and 1.63-fold higher expression in the samples from patients with NSCLC compared to controls, and the difference of expression was statistically significant for miR221 (p=0.000095) but not for miR222 (p=0.084470). In the presence of metastasis in NSCLC patients, miR221 levels were 2.33-fold higher compared to non-metastatic cases (p=0.014), and those of miR221 and miR222 were expressed 1.44 and 1.52-fold higher, respectively, in advanced stage compared to early stage (p=0.000387, p=0.000302).
conclusionThe levels of miR221 and miR222 in the serum of patients could be used as biomarkers for the diagnosis, treatment, and prognosis of NSCLC.
