*Data is about: The effect of Maternal Lipid Levels on Pregnant Women Without Complication in Developing Risk of Large for Gestational Age Newborn

*large-for-gestational (LGA) : Refers to a fetus or infant who is larger than expected for their age and gender.

* Import the stata data file "REVMAN.dta"

*Read Description:
* The data provides mean difference, and standard error of each samples being compared, but does not provide Effect size and standard error for the comparisons!
* An alternative is to use Cohen's d , which is the standard mean difference.
* Hint: use metan with N M Sd of LGA and nLGA!
* Type "help metan" and go to "Meta-analysis of two-group comparison of continuous outcomes, using the sample size, mean and standard deviation in the treatment and control groups"
* The metan of cohen's d can produce the effect size and standard error for you to be later used in the future analysis.
* LGA is the group affected by LGA and nLGA is the group not affected by nLGA

** Important ----> report up to 2 decimals and do not round up or down <----
