====== How to search the literature ======

===== Pubmed =====

- Pubmed is a database with most medical journal articles. 
- The easiest way to get to pubmed with UTHSCSA links for full text articles is to go to [[http://library.uthscsa.edu|library.uthscsa.edu]]. Then click pubmed to go to the pubmed search engine. 

===== Searching for clinical trials =====

You must start with determining the population, intervention, comparator/control, and the outcome you want to search for. 

=== How to do a evidence based research using the PICO methodology ===
P - population I - intervention C - control group/comparator O - outcome

(“child abuse” OR “child neglect” OR “adolescent violence”) AND (CPS OR adoption) AND (substance use OR alcohol OR methamphetamines OR “externalizing disorder”)\\
in the above example we used PICO methodology\\
P = “child abuse” OR “child neglect” OR “adolescent violence” \\ I = (CPS OR adoption) \\ C = no comparator given as there didn't seem to be a clear comparator we could use \\ O  = (substance use OR alcohol OR methamphetamines OR …)
