Give the formula for the Odds Ratio, the 95% Confidence Interval and write how you constructed the Forest Plot  ## Testing for Publication Bias: visual inspection  A Publication Bias was tested by setting up a Funnel Plot. The  Funnel Plot is graphically presented and was created  using the Review Manager Software (RevMan). The Funnel Plot will show (RevMan).This shows  the assumptions that the largest studies will be are  near the average and the small studies will be are  spread on both sides of the average. If there are any variations shown from this assumption there is a likelihood that publication bias exists. A symmetric inverted funnel shape will indicate indicates  well-presented data in which publication bias is very unlikely. And an asymmetric funnel shape will indicate indicates  the relationship between the treatment effect and the study size.Write here that you tested for publication bias by setting up Funnel Plot. Discuss what a funnel plot means and why and how you will use the Funnel Plot to visualise the distribution of studies.  ## Subgroup Analysis
