China is one of the 22 countries with a high-burden of tuberculosis (TB) and has the second highest number of TB patients in the world (World Health Organization, 2013). Osteoarticular TB (OA-TB) is one of the main types of extrapulmonary tuberculosis. There are about 30 million TB patients, of which 1-3% have skeletal involvement (Tuli, 2002), with causes that are directly related to poverty (Cheng, 2011).
The long non-coding RNA MALAT-1 plays an important role in cancer prognosis. The present research aimed to elucidate its precise predictive value in various human carcinomas. A quantitative meta-analysis was performed by searching PubMed, Embase, Web of Science, and Cochrane Library (most recently, January 2015) databases, and extracting data from studies that investigated the association between MALAT-1 expression and survival outcomes in patients of various cancers. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated as a measure of generalized effect.
