More about AND

This Venn diagram illustrates the use of the Boolean operator AND -- the colored area represents the result of the Boolean operation.

In this case multiple AND operators were used to combine more than one concept or term. Only records containing all the terms will be retrieved.

And here's how the search strategy would look using Ovid MEDLINE:

1. Diabetes Mellitus, Type II (33995 records)
2. obesity (59850 records)
3. child (1035163)
4. 1 and 2 and 3 (315 records)


Note: I used MeSH terms in this example.

I skim a lot of blogs, and so far yours is in the Top 3 of my list of favorites. I'm going to dive in and try my hand at it, so wish me luck.

It'll be in a totally different area than yours (mine is about diabetes gestational) I know, it sounds strange, but it's like anything, once you learn more about it, it's pretty cool. It's mostly about diabetes gestational related articles and subjects.
