It was assumed that these indices (calculated based on prevalence data for 2005) applied for all years in the period 2009 2040; this was considered to be reasonable given that the required adjustments were small, although (as noted in Maddams et al (2009)) completeness indices for male lung cancer may have been underestimated.
Based on prevalence curves of urinary incontinence during pregnancy, we categorised age into four age groups (≤26, 27 30, 31 34 and ≥35 years).
Based on prevalence and mortality, the serous carcinoma is the most important, representing nearly 40% of all primary ovarian carcinomas with an overall five-year survival rate of approximately 30%.
This matched almost exactly the predicted 1-day prevalence of 14.6% based on 1-year prevalence and mean frequency in headache days/month (extrapolated from the last 3 months) (Table 1).
In all three earlier published studies of HY, similar internal consistency has been seen between reported HY and prediction of 1-day headache prevalence based on estimated 1-year prevalence and recalled frequency during the preceding 3 months [15 17].
Based on 5 years of biannual prevalence studies a decreasing trend in the prevalence of HAI's and particularly urinary tract infections was observed as well as a decline in percentage of residents having antibiotics.
Models based on birth cohorts show a steeper age pattern of diabetes prevalence than those based on calendar years.
†Malaria endemicity levels based on 2 9 years of available parasite prevalence data, according to the World Health Organization classification: hypoendemic, 0 10%; mesoendemic, 11%50%%; hyperendemic, 51%75%%; and holoendemic, >75% (9 ).
