Among young adult smokers in England, lower-status occupational groups were more likely to use e-cigarettes on a non-daily basis than to have never used compared with higher status occupational groups. Compared with people in full-time employment, those without employment were less likely to use e-cigarettes daily than to have never used.

Numerous published papers are showing correlation of miRNA with metastasis. There is a need to analyze and validate such correlation. English language literature in major databases from the last 20years was searched using controlled vocabulary and keywords. Strict inclusion and exclusion criteria were followed for selection of studies. The quality assessment was done as per the QUADAS tool 2 by three independent reviewers. The metanalysis was performed by using random effect model. Standardized mean difference (SMD) was considered as the effect measure. Statistical software used was STATA version 13.1. With all inclusion and exclusion criteria, eight studies could qualify for metanalysis. The pooled estimate is found to be 0.13 (-0.35, 0.62), P=.585, which is statis
