Epidemiology and Health Outcomes

Section edited by Bernard Jaar and Deputy Section Editor Laura Plantinga

The Epidemiology and Health Outcomes section considers manuscripts describing epidemiological studies relating to the field of nephrology. The section also considers systematic reviews and meta-analyses. Both qualitative and quantitative studies discussing health outcomes research and outcome measures are also considered by this section. Research related to clinical practice guidelines should be directed to the dedicated Guidelines and Policy section.
