Biased prevalence estimates of parameters of interest could be derived from our sample if they were associated with sex, age or educational achievement.
Prevalence of categorical parameters was compared using Fisher's exact test, and correlations were assessed using the Pearson test.
By comparing SDB atopic subjects (60/110) (test group) vs. SDB nonatopic subjects (50/110) (control group), the prevalence of the parameters taken in consideration showed the following: Adenoid hypertrophy: 36% (21/60) in the test group vs. 78% (39/50) in the control group (p = 0. 001) (Table 2).
The prevalence of each parameter of metabolic syndrome among subjects in each group is presented in Table 2.
The prevalence of each parameter was listed based on what was reported in the most authoritative literature we could identify.
The tint is given by the prevalence of the parameter in the disease tested, multiplied by the prevalence in the disease in the database that shares the parameter.
The tint of each square in the center of the cluster map reflects the prevalence of a parameter in the disease based on published literature.
Sample size calculations for cross-sectional studies are based upon the expected prevalence of the parameter under investigation, and small sample sizes may not provide adequate precision.
The great performance of all the SVM's show that the method is robust, and that the prevalence of the clinical parameters can be used to indicate whether a disease show mitochondrial involvement.
We have sized the study using data collected from face-to-face questionnaires, which may have underestimated the true prevalence of sensitive behavioural parameters because of social-desirability bias.
The lower mental HRQoL in younger ED patients in comparison with the representative BGS-data may be partly due to the high prevalence of substance use parameters in ED patients.
