Clinical Research

The Clinical Research section considers both interventional and non-interventional clinical research studies, including, but not limited to, controlled trials and case-control studies. This section does not consider basic experimental research, large epidemiological studies, or case reports. Systematic reviews, meta-analyses and epidemiological studies should be directed to the Epidemiology and Health Outcomes section, and case reports should be directed to our dedicated Case Reports section.
