The very aim of a systematic review is to provide a critical summary of the available evidence. The authors of a systematic review may draw conclusions based on the collected studies on a particular topic. It is equally important to present to their readers an unbiased quality assessment of the included studies in the review, which is an integral part of a systematic review process. This process is what differentiates a systematic review from the rest and a missing quality assessment of included studies section brings it as par with the common narrative or a literature review. The risk of bias and quality assessment of studies included in this review is missing. The onus is on the researchers to provide clear, simple conclusions of studies that has been meticulously checked and rechecked for their validity. Otherwise, on the contrary, it only helps to pollute the current evidence.

It is important to note that;

• Systematic reviews are one of the highest levels of information in the hierarchy of evidence LINK
• Steps involved in a systematic review have been laid down by the Cochrane collaboration STEPS
• A major section involves assessment of quality and risk of bias, of the included studies
• Assessment not only helps in ascertaining validity of a particular study, but also gives a true estimate (over/under) of the intervention (or exposure) Assessment of quality and risk of bias
