Writing systematic review in English language is challenging for those whose first language is other than English and those who are not primarily trained on writing skill such as medical doctors.1 The guidelines to write and publish a systematic review are usually specific to scientific journals or such research groups that publish systematic reviews. Systematic reviews are accepted in most of the medical journals. The top 100 most cited systematic reviews in medical sciences research between 1977 and 2008 have mainly been published in Journal of American Medical Association (JAMA), British medical journal (BMJ) and the Lancet.2 These journals provide guidelines on how to write systematic reviews. There are online resources that promote quality, transparency and standardization on methods of conducting and publishing systematic reviews e.g. The Cochrane review of the Cochrane collaboration; Prospero: International Prospective register of systematic reviews of the center of review and Dissemination of University of York, England;and PRISMA" Preferred reporting items of systematic reviews.In this article a review on methods to write the "introduction and methods sections" of the systematic review is provided. Two international groupshave developed guideline for reporting systematic reviews, known as PRISMA statement and Cochrane handbook on conducing and dissemination the systematic reviews.The PRISMA statement requires that introduction of systematic review should have two parts namely rationale (what is already known in the context) and objective that is a statement to address a particular question.3
