Healthcare decisions for patients and public health policies should be supported by the best available research evidence. To ensure the hierarchy of the evidence, an evidence pyramid was conceptualized, with in-vitro studies and animal studies forming the bottom of the pyramid, expert opinions, case series, case reports, and observational studies forming the middle layer, and […]

Results from over half of all conducted randomized controlled trials (RCTs), especially those with negative or unfavorable results, never get published. This means, searching only electronic databases that index published literature does not provide the entire spectrum of information; additionally, a bias is induced, since most trials having negative results get omitted. This is extremely […]

Systematic reviews (SRs) often face a major challenge while identifying all the relevant research, including randomised controlled trials (RCTs) irrespective of their publication status.(1) Unpublished, selectively reported, or non-reported research can lead to poorer quality clinical trials, thus leading to suboptimal care delivery. It also overlooks the opportunities for potential scientific progress.(2) Such incomplete publication […]

Systematic reviews (SRs) are incredibly crucial for healthcare decision-making, as they often provide a reliable summary of evidence on the comparison among healthcare interventions. They identify, assess, and combine the results of similar but individual studies and help to clarify the known and unknown benefits and risks associated with drugs, devices, and other healthcare interventions. […]

During the course of any research, most of the relevant literature pertaining to a research question is retrieved though searching of recognised databases. However, in addition to this, searching of grey literature can add value to the depth of the research by providing information from varied sources. Grey literature search is an important, but often […]

Systematic literature reviews (SLRs) are widely used to pool and present the findings from multiple studies in a dependable way and are often used to inform policy and practice guidelines. (1) An important SLR feature is the application of scientific tools to find and curtail bias as well as error in the selection and treatment […]
