Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators will carry out a randomised trial of free face mask distribution in Stovner District, Oslo, Norway. Ten grocery stores will serve as study sites. Over three weeks the stores will be randomised daily to having "corona hosts" outside their entrance, handing out face masks to customers. The investigators will compare the proportion of customers who wear face masks as they enter the store in stores with or without face mask distribution.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The team members from the Stovner district-administration will send a numbered list to Norwegian Institute of Public Health-team, with the names of the stores. The ordering of the stores will define the numbers used to represent each store in the randomisation process. Using Stata software, we will carry out 13 separate and independent randomisations, each assigning the intervention to half the included stores. An additional randomisation to the treatment or control group will be carried out for a marginal store each day in the event of an odd number of stores.

Unless it proves too logistically cumbersome, we will also randomise the corona hosts, i.e. the store they are allocated to will be decided through randomisation.
Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

The analyst will receive a dataset in a format which makes it impossible for him/her to know which of the two arms in the dataset represents intervention or control.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Distribution of free face masks

Face masks will be handed out for free to all customers entering the grocery stores.

Group Type EXPERIMENTAL

Distribution of free face masks

Intervention Type BEHAVIORAL

"Corona hosts" will be placed at the entrance of the intervention stores, and hand out face masks to customers entering the store.

Control

Business as usual.
