We examined the relationship between the misconception and the characteristics listed in Table 1 by year of study by using prevalence proportions and unconditional logistic regression.
We calculated autism prevalence rates for white, black and Asian Americans by using total prevalence and relative populations of minors for each ethnic group by state.
The preliminary analyses were carried out by using both the prevalence of overweight and obesity as dichotomous variables and the mean BMI as a continuous variable.
We focused on Lopburi Province which has 11 districts and classified the districts by using the percentage prevalence of alcohol consumption in each district and then categorized as high (more than 10%), medium (6%–10%), and low risk (less than 6%).
The pooled prevalence was calculated by using standard error of prevalence that is given by √[ p×(1− p)/ n], where p is the proportion of prevalence and n is the reported sample size.
Thus, the estimated prevalence rates were calculated by using the proportion of cases or prevalence count of patients, over the total population at a given time.
We estimated SCD prevalence by using the incidence of SCD at birth with adjustment for early mortality from SCD.
By using our estimates of HPV prevalence among pools of sex partners, numbers of new sex partners, sexual mixing patterns, and duration of HPV shedding, we derived estimates for infectivity per infected partner for persons of both sexes in each age group in the absence of a vaccination program.
By using the calculated prevalence ratio of 2.6 as an estimate of the relative risk of dengue in houses without air-conditioning, the proportion of dengue infections attributable to lack of air-conditioning in Nuevo Laredo was 55%, i.e., 55% of cases of dengue in Nuevo Laredo would not have occurred if all households in Nuevo Laredo had air-conditioning.
Matching was done to assure that intervention and control homes were comparable by using the following factors: prevalence of UI and use of incontinence pads, number of residents, percentage of residents receiving psycho geriatric care (i.e. for dementia), number of staff members, percentage of residents with impaired mobility, and average level of care per participant in minutes.
