Research Ethics Policy

Authors must state that the protocol for their research was approved by a suitably constituted Ethics Committee of the institution within which the work was undertaken and that it conforms to the ethical principles set out in the Declaration of Helsinki, as revised in 2013, available at:

The World Health Organization and the Declaration of Helsinki advise that clinical trials are prospectively registered before participants are enrolled. Clinical trial registration numbers should be included in all papers that report on clinical trials.

The journal retains the right to reject any manuscript on the basis of unethical conduct in either human or animal studies. All studies on human subjects must state that the subject gave informed consent. Patient anonymity should be preserved. Photographs must be cropped sufficiently (or an eye bar should be used) to prevent human subjects from being recognized.
