  1. Bookkeeping for size of total prevalent population with respect to anti-diabetic treatment, Fyn County, Denmark, 1994–2003. P is prevalence on Jan 1 of the given year, I is number of incident subjects, C NI is number of persons having discontinued treatment without re-initiation in the given year, C I is number of persons having discontinued treatment who re-initiated treatment within the given year, D 1 is number of deaths among treated, and D Inc is number of incident subjects dying before the end of the year. Diff for year Y is P Y - (P Y-1+ I Y-1- C NI, Y-1- D 1,Y-1- D Inc, Y-1), ie. difference between observed and predicted prevalence. Note, that C I does not enter into the computation of Diff since these subjects both leave and re-enter the prevalent pool of subjects in the same year.
