PURPOSE: Patients with pituitary adenomas often present with visual deficits. While the aim of endoscopic endonasal transsphenoidal surgery (EETS) is to improve these deficits, permanent worsening is a possible outcome. The aim of this meta-analysis was to evaluate the effect of EETS for pituitary adenomas on visual outcomes. METHODS: A meta-analysis was conducted according to the PRISMA guidelines. Pooled prevalence was calculated for complete recovery, improvement, and deterioration of visual field deficits, visual acuity and unspecified visual function in fixed- and random-effect models, including assessment of heterogeneity (I(2)) and publication bias (Begg's test)...

The relationship between abdominal aortic calcification (AAC) and bone fracture has been examined by some observational studies, but the results remain discordant. Therefore, we aimed to assess the link between them by conducting a meta-analysis of prospective studies. Relevant studies were identified by searching PubMed and EMBASE databases until the end of December 2016. Summary relative risks (RRs) and 95% confidence intervals (CIs) for associations between AAC and fracture risk were estimated with fixed- or random- effects models...

The polymorphism of lipoprotein lipase (LPL) gene Ser447Ter (S447X) has long been linked to hypertension and blood pressure variation, but the established data remained controversial. To better elucidate this inconsistency, a meta-analysis was conducted. We comprehensively searched electronic databases, including Pubmed, EMBASE, China National Knowledge Infrastructure (CNKI), Web of Science, for all literatures with the last update on February 2016. The strength of association was calculated by using odds ratios (ORs) and weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs)...

A large meta-analysis by Anderson et al. (2010) found that violent video games increased aggressive thoughts, angry feelings, physiological arousal, and aggressive behavior and decreased empathic feelings and helping behavior. Hilgard, Engelhardt, and Rouder (2017) reanalyzed the data of Anderson et al. (2010) using newer publication bias methods (i.e., precision-effect test, precision-effect estimate with standard error, p-uniform, p-curve). Based on their reanalysis, Hilgard, Engelhardt, and Rouder concluded that experimental studies examining the effect of violent video games on aggressive affect and aggressive behavior may be contaminated by publication bias, and these effects are very small when corrected for publication bias...

Violent video games are theorized to be a significant cause of aggressive thoughts, feelings, and behaviors. Important evidence for this claim comes from a large meta-analysis by Anderson and colleagues (2010), who found effects of violent games in experimental, cross-sectional, and longitudinal research. In that meta-analysis, the authors argued that there is little publication or analytic bias in the literature, an argument supported by their use of the trim-and-fill procedure. In the present manuscript, we reexamine their meta-analysis using a wider array of techniques for detecting bias and adjusting effect sizes...
