Was point or period prevalence reported on in the prevalence related article?
If period prevalence, what time period was used?
What type of incidence was reported on in the incidence related article?
What was the time period used?
In each of the articles, in your opinion, was the denominator appropriate? Why or why not?
In each of the articles, in your opinion, was the case definition (numerator) appropriate? Why or why not?
Did the authors’ conclusions seem valid based on the study they reported? Why or why not?
