english: For many years, because there was no standardization in the definition of PMS, when psychologists tried to report prevalence rates, their estimates ranged from five percent of women to 97 percent of women, so at the same time almost no one and almost everyone had PMS.
non_english: Godinama, pošto nije bilo standardizacije definicije PMS-a, kada su psiholozi pokušali da naprave izveštaj o stopi rasprostranjenosti,  njihove procene su se kretale od pet posto žena do 97 posto žena, tako da istovremeno skoro da niko nije imao PMS i skoro svi su ga imali.
