Objectives: To investigate the methodological quality in meta-analyses (MAs) published in behavioral and social sciences. Methods: We evaluated a random sample of 207 MAs indexed in PsycINFO database in 2016. Two authors independently extracted methodologic characteristics of all MAs with the 16 items of AMSTAR2 (A MeaSurement Tool to Assess system...
Objectives: To investigate the effect of the explicit use of PRISMA, a statement designed to help authors to report meta-analyses (MAs), on the reporting quality of MAs in behavioral and social sciences. Methods: We evaluated a random sample of 207 MAs indexed in PsycINFO in 2016; 100 explicitly used PRISMA and 107 did not. Two authors independentl...
Abstract Purpose: To evaluate the prevalence of excessive screen-based behaviors among Brazilian adolescents through a systematic review with meta-analysis. Data source: Systematic review and meta-analysis were recorded in the International Prospective Register of Ongoing Systematic Reviews (PROSPERO-CRD 2017 CRD42017074432). This review included o...
ABSTRACT BACKGROUND: There is increasing evidence to show that TNF-α -308G>A polymorphism may be a risk factor for celiac disease, but the results are inconsistent. OBJECTIVE: Thus, we aimed to perform a meta-analysis involving published studies up to January 2019 to elucidate the association. METHODS: To assess the effect of TNF-α -308G>A polymorp...

Background: Is the prognosis of immunoglobulin A nephropathy (IgAN) influenced by pregnancy and delivery? The answer to this question still remains to be a controversial topic. Here, we undertook a systematic review and meta-analysis to obtain the overall estimate of potential effect of IgAN and pregnancy on each other. Methods: We systematically s...

Background: The preferred type of postremission therapy (PRT) for intermediate-risk acute myeloid leukemia (AML) in first complete remission (CR1) is a subject of continued debate. Although allogeneic stem cell transplantation (alloSCT) is regarded as a curative strategy for AML, the efficacy of autologous stem cell transplantation (autoSCT) for pa...
Vegetable production is recognized as an important anthropogenic source of nitrous oxide (N2O) emission. An improved understanding of yield-scaled N2O emission from vegetable production can promote innovation for climate smart cropping. In this study, we performed a meta-analysis to quantify yield-scaled N2O emission from six types of vegetable cro...
50% depending on the countries and the groups of population. Such discrepancies can be attributed to the type of serological assay used, but this solves only a part of the problem. We performed a meta-analysis of studies performed with the broadly used Wantai HEV-IgG ELISA and found striking differences that remain difficult to understand with the ...
