The prevalence of selected underlying chronic illnesses was estimated based on Canadian survey data [ 28, 29], with the exception of the prevalence of chronic kidney disease, which was determined by United States survey data [ 30].
With the exception of the prevalence of the polymorphisms, which was reported in the majority of HuGE reviews and one-third of the others, such data were rarely given.
Participant characteristics were comparable between the two treatment groups in both men and women, with the exception of higher prevalence of overweight or obesity among women in the vitamin K treated group.
Due to a lack in data, it was not possible to project the prevalence of eye diseases among the younger population; however, with the exception of myopia, the prevalence of eye disease among the young is likely to be much lower than that among the population over 40 years.
At follow-up, prevalences of single and mixed S. haematobium infections significantly decreased with the exception of Koulikoro where prevalence of single S. haematobium infections significantly increased.
With the exception of a lower prevalence of sleep disturbances among the men in the study group (23% compared to 27%) the prevalence of mental health symptoms at baseline was about the same among the dropouts and those who remained in the study.
With the exception of elderly women, prevalence rates of vitamin D insufficiency were lower in the summer/higher latitude subpopulation (<1%–3% with 25-OHD <25 nmol/L to 21%49%% with 25-OHD <62.5 nmol/L).
In addition, with the possible exception of ETV1, whose prevalence of overexpression was about 2-fold higher in the SYS cases, none of the genes seemed to be associated with systemic progression of prostate cancer.
Although the rates were lower, a similar pattern of use was observed for long-term HRM with the exception of nitrofurantoin whose prevalence was negligible (Additional file 3).
