It appears this was done on intake, so the control group started receiving standard-of-care and the other group received standard-of-care + LAC + PEA. Since both groups were starting treatment, it seems to me a placebo would be less necessary, especially considering the control group is likely starting other supplements. (e.g. vitamin d, magnesium, iron)
comments
Was the LAC and PEA administered blind, and was the control group given a placebo?
