  1. Cell frequencies represent the reports by contact duration for pairs of participants. That is, participant A’s and participant B’s reports about their contact with each other comprise a single observation in the table. Columns give the higher contact duration report, and rows show the lower report. If a contact was reported by only one participant in a pair, then the lower duration value is ‘not reported’. Each percentage within a cell represents percentage of the row (right) and column totals (lower).
