		<description>Hi Kate,
I am glad you came by, and that you found my post of use :)
Regarding your comment, it sounds worth while, and I could make the change in the graph I made - BUT - since my graph is based on the data from informationisbeautiful, wouldn&#039;t it be better to offer this to them, so that their table will include the correction? (I already noticed they respond to comments from the audience, I think it would be worth to you to jump over to their post and leave there your comment)

All the best,
Tal</description>

		<description>Great work, and a nice complement to the informationisbeautiful.com infographic. One little quibble is that you used &quot;gyno&quot; as the general category for folic acid. I think it would make more sense to say obstetric, since folic acid affects fetal development, not general reproductive health. I think the gyno tag would work better for supplements that affect PMS/menstrual cramps/etc.</description>

		<description>Hi Tal,
Nice code! I use part of it to plot a ballon plot using Hadley Wickham&#039;s ggplot2 package. See the plot at this link:

		<description>Hi J S - 

Selenium got both 6 and 3 because it has different level of evidence for different aspects of helping patients with cancer.

The google spreadsheet indicates that Selenium is &quot;3&quot; for &quot;cancer&quot; but &quot;6&quot; for chemotherapy.  I didn&#039;t got into the details of the difference, but you can review the source for the info here: http://www.ncbi.nlm.nih.gov/pubmed/9290116

For the grade 6, the source abstracts are:
#  Russo, M. W.; Murray, S. C.; Wurzelmann, J. I.; Woosley, J. T.; Sandler R. S.; (1997). &quot;Plasma selenium levels and the risk of colorectal adenomas&quot;. Nutr Cancer. 28 (2): 125–129.. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&amp;db=PubMed&amp;list_uids=%209290116.                                               Patterson, B. H.; Levander O. A. (1997). &quot;Naturally occurring selenium compounds in cancer chemoprevention trials: a workshop summary&quot;. Cancer Epidemiol Biomarkers Prev. 6 (1): 63–69. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&amp;db=PubMed&amp;list_uids=8993799.

While for grade 3 , the source abstracts is:
Russo MW, Murray SC, Wurzelmann JI, Woosley JT, Sandler RS (1997). &quot;Plasma selenium levels and the risk of colorectal adenomas&quot;. Nutrition and Cancer 28 (2): 125–9. doi:10.1080/01635589709514563. ISSN 0163-5581. PMID 9290116

If after reading you come up with a deeper understanding, please feel welcome to share.
