I know RTC is random control trial, I know MD is mean difference, I know CI is confidence interval, RR is risk ratio. But I still have no way of imagining the difference being described here.

>2.4.7 Prolactin - mean change from baseline in ng/ml
>Risperidone was associated with clearly more prolactin increase than aripiprazole (2 RCTs, n = 383, MD 54.71 CI 49.36 to 60.06).

HOW MUCH CHANGE MOTHER FUCKER? How many ng/ml?
