Hi,
Hope the question is not too simple. I am trying to make sense of
a paper that has given a pre-intervention value and the degree of
change following intervention (expressed as a percentage difference) I
am trying to figure out if the change is significant. Specifically:
Pre intervention value is 120+/-41. After intervention, the author
reports a change of 98+/-41%. n is 11. The footnote mentions all
figures are mean +/- SE. Is it possible to recreate the post
intervention mean and SE from this so I could use a t-test? Are there
other ways to say this is statistically significant or not?
Thanks in anticipation,
Anil
