Seventy-five per cent of patients completed all three visits despite the high geographical mobility of the affected age group and the lack of clinical advantages associated with the follow-up visit.
The population prevalence of probable nodding syndrome among children of the affected age group in the study area has been estimated as 6.8 (95% CI 5.9 to 7.7) per 1000.
Even when it was illegal to leave a child of the affected age home alone for 4 h (Fig. 1d), the additional presence of an injury to the child increased the percentage of respondents that determined the situation child neglect when 10 12 year olds were involved as compared to when there was no injury to the child.
Nonetheless, children 9 11 months of age were one of the most affected age groups during the 2010 outbreak.
Taken together with molecular evidence of dengue endemicity in Angola (7, 8 ), these observations indicate a level of dengue endemicity equivalent to that observed in the Americas (4 ), where adolescents are routinely one of the most affected age groups (19 – 219).
According to the age distribution of oral cancer patients, affected age was 60 or more (55 patients, 65%%).
Age stratified syndromic surveillance with a multivariate space-time scan statistic [29] may further facilitate quick interpretation of clusters by revealing the affected age groups.
The standardised survey methodology known as RAAB (rapid assessment of avoidable blindness) was developed in order to systematically assess the magnitude and causes of blindness in the most affected age groups, i.e., the population aged over 50.
Adjustment for other variables (i.e. number of affected vessels, age, sex, smoking, BMI, LDL- and HDL-cholesterol) was performed by adding those covariates in a set of multiple logistic-regression models.
Odds ratios with 95% CIs were estimated by univariate logistic regression analysis and then by multiple logistic regression with adjustment for number of affected vessels, age, sex, smoking, BMI, LDL- and HDL-cholesterol.
