Therefore, prevalence rates must be interpreted as period prevalence
estimates over the course of several years, rather than point estimates at a single cross-section in time (Thomas and Wannell 2009).
All these considerations suggest that the validityofthe period prevalence estimates M1 and M2 are not affected by a lack of standardization in blood data acquisition.
Second, the period prevalence estimates are independent of the doping protocol and, more particularly, its duration.
The seven-day period prevalence and associated burden of symptoms was measured using the Memorial Symptom Assessment Scale Short Form (MSAS-SF).
Seven-day period prevalence and burden of symptoms (N = 378) Distress, n (% *) Physical symptoms Prevalence N/A None Numbness/tingling 226 (59.
Because of the lack of distinction between pain prevalence other than pain "right this minute" and period prevalence
, reports on period prevalence
for a period of up to 1 year prior to the date of data collection were included.
Hence, the present study was carried out with the objectives of finding the period prevalence
of dog bites, risk factors and treatment seeking behaviour among children.
Thus, the minimum 11-year period prevalence
of RLM was 2.
By region, 1-year period prevalence
estimates ranged from 6.
Because of this variability and the low number of annual cases in some states, tabular rates are presented as period prevalence
One-year period prevalences
of single symptoms were 1-40%, annual incidence values 1-25% and 5-year disappearance rates were more than 50%.
