nanocrystalline particles of cerium oxide (ceo2) have been prepared by the chemical precipitation method using cerium nitrate and urea with a molar ratio of 1:2. the results revealed that the formation of ceo2 fine particles is influenced by molar ratio of metal nitrates to fuel. well faceted ceo2 nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a...

When multiple parameters are estimated from the same synthesis model, it is likely that correlations will be induced between them. Network meta-analysis (mixed treatment comparisons) is one example where such correlations occur, along with meta-regression and syntheses involving multiple related outcomes. These correlations may affect the uncertainty in incremental net benefit when treatment op...

This study aimed to conduct a mixed-methods SR of the literature investigating experiences (knowledge, attitudes, practices, and effects use) concerning dental dam cling film use. The methodology was informed by Preferred Reporting Items for SRs Meta-analysis framework, Cochrane Handbook Interventions, Joanna Briggs Institute guideline conducting SRs, PICO (population, intervention (or exposure...

In this paper, we conduct a meta-analysis using 1429 estimates extracted from 61 English and Chinese studies to estimate the wage effect of secondary tertiary education in China. The meta-synthesis results show that impact on levels is about twice education. test for publication selection bias confirm literature contains genuine empirical evidence.

MOTIVATION Meta-analysis of summary statistics is an essential approach to guarantee the success of genome-wide association studies (GWAS). Application of the fixed or random effects model to single-marker association tests is a standard practice. More complex methods of meta-analysis involving multiple parameters have not been used frequently, a gap that could be explained by the lack of a res...

We present ontological meta-analysis and synthesis as a method for reviewing, mapping, and visualizing the research literature in a domain cumulatively, logically, systematically, and systemically. The method highlights a domain’s bright spots that have been heavily studied, the light spots that have been lightly studied, the blind spots that have been overlooked, and the blank spots that have ...

BACKGROUND Meta-analyses may be prone to generating misleading results because of a paucity of experimental studies (especially in surgery); publication bias; and heterogeneity in study design, intervention and the patient population of included studies. When investigating a specific clinical or scientific question on which several relevant meta-analyses may have been published, value judgments...

In recent years, progress and innovations in healthcare are measured by evidence-based medicine (EBM), systematic reviews, and meta-analyses. A systematic review is defined as, "the application of scientific strategies that limit bias by the systematic assembly, critical appraisal, and synthesis of all relevant studies on a specific topic." In contrast, meta-analysis is the statistical pooling ...
