Compute a mean effect size and its confidence limits Kapoor
Compute a mean effect size and its confidence limits. Kapoor et al. (2010) collected data on the treatment of multiple myeloma, which is a cancer of the blood.
(You may think that this has little to do with psychology, and you’d be right, but I have multiple myeloma, so I have a particular interest in the results.) They found four studies since 2007 that compared a standard chemotherapy treatment for myeloma with the same treatment that also included thalidomide.(Thalidomide was a drug prescribed as a sedative to pregnant women in the 1950s and was then found to create horrible problems with birth defects and was immediately withdrawn, but not until after causing 10,000–20,000 birth defects worldwide. It has recently been found to be an excellent treatment for some forms of cancer, though it is used with a great deal of caution.) The following table presents the results of the four studies.
