Two loci out of seven were significantly negative for cluster 2 and two out of six were significant for cluster 3. Overall, a large proportion of H values were negative throughout the three strains, indicating a prevalence of high frequency, derived segregating alleles.
These findings are similar to the results of Sun et al. [ 7]. van Brummen et al. [ 2] reported a high prevalence of frequency and urgency symptoms at 12 weeks of gestational age and that these symptoms then remained stable during the other two trimesters.
Moreover, it was found a prevalence of EEG power in the high frequency ranges (beta-1 and beta-2) upon awakening from stage 2 compared to REM awakenings over the left anterior derivations.
The increase of this haplotype frequency causes a prevalence of negative effects on fitness from genes B and C, averting the fixation of all mutations within this haplotype.
A recent study from Brazil stratified bullying by frequency, with a prevalence of 5.4% reporting "often and very often being victimized", and 25.4% "sometimes or rarely being victimized" in the last 30 days [ 3].
The present findings therefore suggest that the wake EEG in the chronic state maintains some key characteristics of the acute phase, namely, a greater prevalence of lower frequencies and a hemispheric dissymmetry in the beta range.
We defined frequency as more than 8 voids per day and nocturia as more than one void per night (as in some earlier reports [3] [5], [18]) while those definitions are presumably clinically more relevant based on prevalences of frequency and nocturia in earlier studies [9], [16], [26], [27].
We observed a greater prevalence of low/mid-frequency hearing impairment among unmarried subjects.
The multiparous pregnant women had higher prevalence rates of frequency and nocturia compared with the nulliparous women, which is comparable to the report of Stanton et al. [ 14].
Increasing prevalence rates of frequency, nocturia, SUI, and incomplete emptying were reported with gestational age in both the nulliparous and multiparous women.
