How Does the Waterlogging Regime Affect Crop Yield? A Global Meta-Analysis.

Waterlogging, an abiotic stress, severely restricts crop yield in various parts of the world. Thus, we conducted a meta-analysis of 2,419 comparisons from 115 studies to comprehensively evaluate the overall change in crop yield induced by waterlogging in the global region. The results suggested that waterlogging obviously decreased crop yield by 32.

No significant association between immunosuppression in solid organ transplantation and prostate cancer risk: a meta-analysis of cohort studies.

Background: It is known that organ transplant recipients have a significantly higher risk for developing cancers, but the association between immunosuppression in organ transplantation and the risk for prostate cancer (PCa) remains unclear. We aimed to assess the evidence regarding the association of solid organ transplantation with PCa risk.

Methods: A literature search of the PubMed, Embase, and Web of Science databases was performed up to March 2019.

[Vasectomy does not increase the risk of prostate cancer in Chinese men: A meta-analysis].

Objective: To investigate the correlation of vasectomy with the risk of prostate cancer in Chinese men.

Methods: We systematically searched the databases CNKI, VIP, Wanfang, PubMed, Embase, and Cochrane Library for the literature relating the relationship between vasectomy and the risk of prostate cancer in Chinese males up to December 2014. According to the inclusion and exclusion criteria, two investigators independently selected the eligible publications, evaluated their quality, and extracted relevant information, followed by a meta-analysis with the software STATA 12.

Associations of dietary patterns with the risk of all-cause, CVD and stroke mortality: a meta-analysis of prospective cohort studies.

Considerable controversy exists regarding the associations of dietary patterns with the risk of all-cause, CVD and stroke mortality. Therefore, a meta-analysis was conducted to elucidate the potential associations between dietary patterns and the risk of all-cause, CVD and stroke mortality. The PubMed database was searched for prospective cohort studies on the associations between dietary patterns and the risk of all-cause, CVD and stroke mortality published until February 2014.
