The motivation for developing CURSI was the assumed inaccuracy of the criteria age and blood pressure of CURB-65 with reference to the high prevalence of hypertension in elderly patients and the low correlation between chronological and biological age [ 16].
Expectedly with reference to the population under study, the prevalence of chronic changes on MRI was low.
With concern for possible interest bias among responders, we also calculated prevalences with reference to the target sample of 7889 pupils: UdH 26.2%; migraine 23.9% (definite 6.5%, probable 17.4%); TTH 11.6% (definite 6.2%, probable 5.4%); pMOH 0.8%; other headache on ≥15 days/month 3.0%; unclassifiable headache 0.5%.
With reference to caries prevalence in the treated schoolchildren, the dmft was 2.01 (SD = 2.06), DMFT was 0.44 (SD = 1.22), and 132 (24.2%) of the schoolchildren had more than one affected tooth (> 1 carious teeth).
The epidemiological data with reference to prevalence were obtained from each national statistics database, except for France (Ricci et al) 25 and Germany (Heidemann et al).
Perhaps Mormons have been relaxed because the musical, written by Robert Lopez with Trey Parker and Matt Stone (makers of the spectacularly transgressive South Park), is pan-offensive: there are jokes about Christians, Jews, homosexuals, Starbucks and, frequently, Africans, including references to the prevalence of Aids and of female genital mutilation on the continent.
As the sensitivity of a surveillance system depends on the prevalence of infection in the population, evaluation needs to be performed with reference to a selected population prevalence of infection, or 'design prevalence' [ 30], which is specified at the infection status node of the scenario tree.
Among currently married women, the questions were asked with reference to their husbands, with the goal of estimating IPV prevalence for the 12 months preceding the survey.
With reference to Nigeria, our results contrast with the prevalence of 8% recorded in a similarly sized sample (n = 153) of A. variegatum ticks collected from cattle in the same part of the country (3 ); this discrepancy might be the result of previous targeting of the rickettsial 16S rDNA gene.
With reference to sexual and reproductive behaviour, HIV prevalence was higher among women who had their first sexual intercourse before their 15th birthday or from their 25th birthday, and/or who had experienced premarital childbearing.
