Keeping track of was over using weekly with the-website check outs into the Alonso Suazo Fitness Cardio from the web site planner, who can over per week profile that will be submitted to the brand new Investigation Cardiovascular system. Analysis Cardiovascular system teams often carry out weekly keeping track of phone calls for the webpages planner to discuss web site accounts and will establish a week conclusion reports, which will be submitted to the principal Detective and studies matching center. Inside site visits, supply investigation and you may biological examples confirmation would-be did within the ten % off instances and you may 10 % out of controls. The storage and you can lab methods would be audited as well.

Specific point 1

The fresh new sandwich-cohort of two hundred females allows us to size an effective seroprevalence of 5 % which have an effective 95 % depend on interval out-of + ? 3 %.

Certain point dos

And if a 2 % volume away from microcephaly, we imagine one 40 instances and you may a sandwich-cohort of two hundred females will provide all of us 80 % stamina (0.05 leader level) so you can place a chances proportion (OR) of 5 for the connection ranging from ZIKV problems and microcephaly, if your incidence from ZIKV issues is 5 % (Fig. 1). A higher incidence regarding ZIKV problems would increase the stamina.

Number of cases (N) necessary by the regularity of ZIKV infection and you will chance proportion (OR) of one’s association having microcephaly (step 3 control, electricity 0.8, alpha 0.05, maybe not matched)
