Musharraf's appearance came just days after Pakistan's federal intelligence agency sent a second reminder to Interpol to arrest the former president, who it says is a "proclaimed offender" in the assassination of Benazir Bhutto in 2007.

After 1 week, a first reminder was sent out, followed by a second reminder a week later.

We investigated whether a prenotification letter instead of a second reminder and varying senders of the questionnaires would affect response rates.

Three weeks after the first email contact, consumers were sent a reminder to complete the survey, and 3 weeks after the first reminder, they were sent a second reminder email to complete the survey following a modified version of Dillman et al.'s Tailored Design Method [35].
For those who still did not respond two weeks later, we sent a second reminder by fax when a fax number was available and attempted a phone contact as a reminder if a phone number was available.
A second reminder was sent 10 days later.
After a first and a second reminder, all participants who have returned the questionnaire are randomised.
