burgeps Anees 2004
Cedd Burge Burge 2009 A minimum of four time point comparisons were needed (only 43% of available records). This equates to a minimum of four readings per day for 3 work and 3 rest days, as long as readings taken at the same times every day. 6-8 readings per day for 5 work days (1 week) and 4 rest days (2 weekends) should be requested from patients. Patients need to wake up at similar times on work and rest days.
