“…We used a software program named 'comprehensive metaanalysis' for the majority of our analyses (Borenstein, Hedges, Higgins, & Rothestein, 2009). The program was chosen because it is one of the most widely used software programs specialized for meta-analysis (Bax et al, 2007). Correlations between L1 and L2 with regard to the target domains such as phonological awareness, decoding, vocabulary, and morphological awareness were entered into predefined data sheet in the program together with the study name and sample size of each study.…”

Cross-linguistic transfer embodies language learners' use of linguistic knowledge of their first language to leverage the learning of a second language. The cross-linguisitc transfer between Chinese and English has been studied by scholars from different disciplines. However, variances and inconsistencies exist among prior studies regarding the investigated linguistic domains and reported results. Therefore, a meta-analysis is needed to systematically investigate the cross-linguistic transfer between Chinese and English. This meta-analysis presents research on cross-linguistic transfer between the two languages in four domains: phonological awareness, decoding skills, vocabulary, and morphological awareness. Using 33 articles conducted in different countries, our results show small to moderate levels of transfer in the above four domains. In addition, it was found that the results were moderated by geographic location of the study and participant age. Overall, the meta-analysis indicates that English and Chinese share common linguistic features that can allow for transfer in learning between the languages. Bilingual learners can benefit in educational environments that tap into these linguistic features.

“…Many studies have previously investigated the association between TNF-α G-308A polymorphism and MI risk, but have yielded inconsistent results. Meta-analysis is a useful method to combine various single studies to obtain a larger sample size (Bax et al, 2007;Zeng et al, 2015a), and has been widely used in genetic association studies (Leng et al, 2013;Mao et al, 2013;Yan et al, 2014;Suo et al, 2015;Zeng et al, 2015b). In the present study, we performed a metaanalysis to evaluate the association between TNF-α G-308A polymorphism and MI risk.…”

Association between TNF-α rs1800629 polymorphism and the risk of myocardial infarction: A meta-analysis

ABSTRACT. The tumor necrosis factor-alpha (TNF-α) G-308A polymorphism has been suggested to be a susceptibility factor for myocardial infarction (MI). However, differing results from various studies have led to controversial conclusions. Hence, we performed a meta-analysis to evaluate the association between TNF-α G-308A polymorphism and MI. Reported studies published before March 30, 2015 were included and analyzed from the PubMed and Embase databases. Study selection and data extraction were carried out independently by two authors. The odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the association between the selected variables using the Comprehensive Meta-Analysis v2.2 software. In total, 12 publications with 13 case-control studies consisting of 6037 cases and 7262 controls However, when subgroup analysis was performed according to the stages of MI, results indicated that there was a significant association between TNF-α G-308A polymorphism and the risk of acute MI. Other subgroup analyses revealed no significant associations. Current evidence suggests that TNF-α G-308A polymorphism may be associated with increased risk for acute MI.

“…Studies describing the multivariate analysis by relative risk or hazard ratio were not combined. The Meta-DiSc software, version 1.4 (Universidad Complutense, Madrid, Spain) 9 was used for the statistical analysis, except for the combination of odds ratios, when the Comprehensive Meta-Analysis, version 2 (Biostat, Inc, Englewood, NJ, USA) 10 was used.…”

Despite the association between high-sensitivity C-reactive protein (CRP) and recurrent events in non-ST elevation acute coronary syndromes (ACS), routine determination of this marker has not been recommended.In order to verify whether the current scientific evidence justifies the inclusion of CRP for risk stratification at hospital admission of patients with ACS, we carried out a systematic review and meta-analysis of the studies indexed in MEDLINE, SciELO or LILACS, with the following inclusion criteria: prospective cohort design and assessment of the prognostic value of CPR, as measured using a high-sensitivity method at the moment of hospital admission of patients with ACS. Nineteen studies met the inclusion criteria.In relation to the long-term follow-up, there was a consistent association between CRP and cardiovascular events, with an overall odds ratio (OR) of 4.6 (95% CI = 2.3 -7.6) and overall multivariate OR of 2.5 (95% CI = 1.8-3.4). As for the short-term, nine studies were positive and six were negative, with an overall OR of 1.65 (95% CI = 1.2-2.3). The overall multivariate OR was not obtained for the short-term follow-up, because this measurement was described only in three heterogeneous studies. Only two short-term studies analyzed the incremental predictive value of CRP in relation to multivariate models, with contradicting results.In conclusion, the small number of assessments of the incremental value of CRP, in conjunction with controversial results regarding the independent predictive value of CRP for short-term events does not support the recommendation of the routine use of CRP for risk stratification at admission of patients with ACS.
