In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

Input: Consider Input: Abstract: BACKGROUND Tuberculosis (TB) has been reported to be associated with poverty, especially in developing countries. Hong Kong is one of the few industrialised areas with a high incidence of TB where previous reports on the effect of poverty at neighbourhood level have been conflicting.
OBJECTIVE To examine the spatial distribution of TB and its association with neighbourhood risk factors.
METHOD A total of 17 294 TB cases notified from 2005 to 2007 were mapped down to the District Council Constituency Area (DCCA) level, and were indirectly standardised by age and sex using 2006 census population data. The standardised TB ratio was correlated with neighbourhood risk factors classified by family, ethnicity, economic and environmental domains.
RESULTS The indirect age- and sex-standardised ratio demonstrated a spatially varied pattern, and was significantly associated with all neighbourhood factors on univariate analysis. Only marital status, place of birth and low household income were independently associated with the standardised TB ratio on multivariate analysis.
CONCLUSION Despite the virtual elimination of absolute poverty by a well-developed social assistance scheme, low household income in the neighbourhood was significantly associated with TB, independently of place of birth, marital status and other risk factors..

Input: Consider Input: Abstract: OBJECTIVE To compare the relative risks of serious gastrointestinal complications reported with individual non-steroidal anti-inflammatory drugs.
DESIGN Systematic review of controlled epidemiological studies that found a relation between use of the drugs and admission to hospital for haemorrhage or perforation.
SETTING Hospital and community based case-control and cohort studies.
MAIN OUTCOME MEASURES (a) Estimated relative risks of gastrointestinal complications with use of individual drugs, exposure to ibuprofen being used as reference; (b) a ranking that best summarised the sequence of relative risks observed in the studies.
RESULTS 12 studies met the inclusion criteria. 11 provided comparative data on ibuprofen and other drugs. Ibuprofen ranked lowest or equal lowest for risk in 10 of the 11 studies. Pooled relative risks calculated with exposure to ibuprofen used as reference were all significantly greater than 1.0 (interval of point estimates 1.6 to 9.2). Overall, ibuprofen was associated with the lowest relative risk, followed by diclofenac. Azapropazone, tolmetin, ketoprofen, and piroxicam ranked highest for risk and indomethacin, naproxen, sulindac, and aspirin occupied intermediate positions. Higher doses of ibuprofen were associated with relative risks similar to those with naproxen and indomethacin.
CONCLUSIONS The low risk of serious gastrointestinal complications with ibuprofen seems to be attributable mainly to the low doses of the drug used in clinical practice. In higher doses ibuprofen is associated with a similar risk to other non-steroidal anti-inflammatory drugs. Use of low risk drugs in low dosage as first line treatment would substantially reduce the morbidity and mortality due to serious gastrointestinal toxicity from these drugs..

Input: Consider Input: Abstract: Countries have reached universal health coverage by different paths and with varying health systems. Nonetheless, the trajectory toward universal health coverage regularly has three common features. The first is a political process driven by a variety of social forces to create public programmes or regulations that expand access to care, improve equity, and pool financial risks. The second is a growth in incomes and a concomitant rise in health spending, which buys more health services for more people. The third is an increase in the share of health spending that is pooled rather than paid out-of-pocket by households. This pooled share is sometimes mobilised as taxes and channelled through governments that provide or subsidise care--in other cases it is mobilised in the form of contributions to mandatory insurance schemes. The predominance of pooled spending is a necessary condition (but not sufficient) for achieving universal health coverage. This paper describes common patterns in countries that have successfully provided universal access to health care and considers how economic growth, demographics, technology, politics, and health spending have intersected to bring about this major development in public health..
