All in all, 2677 LBQ people participated in the LezParlay battle, with five hundred LBQ drinkers hired towards the effectiveness demonstration. Studies clean and research was in fact delay by several days because of COVID-19�related delays and that is underway since . The outcome are expected are published in summer 2021.

A purpose-to-clean out strategy will be accustomed look at LezParlay cures effects on 2 and 4 months postintervention with the 4 outcomes: substance alcohol fool around with, projected amount of products weekly, height number of products into step 1 celebration, and you will quantity of bad alcoholic beverages-associated consequences.
