Association of acute kidney injury with the risk of dementia: A meta-analysis protocol

Abstract Acute kidney injury (AKI) is a complex disorder characterized by an abrupt decline in kidney function over a short period of time. Published epidemiological studies linked AKI with the development of dementia. This meta-analysis aims to understand the pooled risk of dementia in AKI patients compared to non-AKI patients. MEDLINE and Embase databases, and the grey literature in five sources were searched to identify the studies assessing the association of AKI with dementia. The Newcastle-Ottawa scale (NOS) will be used to determine the quality of included studies. The primary outcome of this study will be the risk of dementia among AKI patients compared to non-AKI patients. Subgroup analysis and sensitivity analysis will also be performed. Review Manager version 5.4.1 will be used to perform the meta-analysis.
