EDITORIAL (By Invitation)

An Editorial aims to stimulate thought (often with more questions than answers) rather than review the subject exhaustively. Editorials are usually linked to one or more articles published in the same issue. Personal opinion and comment are legitimate since the Editorial is not anonymous, though of course such opinion needed to be reasonable and backed up by appropriate evidence.

Word count: up to 1200-1500 words.

Illustrations/Tables: no tables and/or figures.

References: up to 15.

These represent a substantial body of laboratory or clinical work. Extended reports should not exceed 5000 words plus references; articles that exceed this word limit may be returned for revision before peer review. Additional data may be presented as supplementary information, which will be published online only should the article be accepted (this can be in any format: text, tables, images, etc.).
