V\u00fdskum za\u010dal so skupinou viac ne\u017e 1 800 star\u0161\u00edch dospel\u00fdch. Po sp\u00e1rovan\u00ed podobn\u00fdch \u00fa\u010dastn\u00edkov ostalo 273 u\u017e\u00edvate\u013eov doplnkov a 546 \u013eud\u00ed bez nich. Sledovanie trvalo pribli\u017ene p\u00e4\u0165 rokov.

Z\u00e1rove\u0148 treba myslie\u0165 na to, \u017ee ne\u0161lo o experiment, ale o pozorovanie, vedci teda sledovali s\u00favislosti, nie priamu pr\u00ed\u010dinu. Nedok\u00e1zali presne kontrolova\u0165 d\u00e1vky, kvalitu doplnkov ani to, \u010di niektor\u00e9 oleje neboli zoxidovan\u00e9. To v\u0161etko mohlo v\u00fdsledky ovplyvni\u0165.
