Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment took place between 16/6/2010 and 16/2/2012. A pool of 12 volunteers was required. 12 volunteers were recruited in 2010 and 2011, 3 further volunteers recruited in 2012 to replace 3 volunteers who left the study for personal reasons.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
There were no significant events required following enrollment.

Reporting Groups

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Volunteers were required to donate saliva for ex-vivo study, as described in protocol. A pool of 12 volunteers was maintained. 3 further volunteers had to be recruited following 3 losses due to personal reasons, i.e. not connected with study.
