Because we are observing new cases of disease in a cohort study, what kind of relationship may we establish? Group of answer choices Confounding Temporal Positive Negative Why might there be uncertainty with the association between an exposure and disease in an observational study? Group of answer choices The association may be due to the factors that led people to be exposed (e.g. confounders) rather than the exposure itself. Case-control studies are more valid, so they should be the standard...

Objectives. This study aimed to clarify the relationship between community water fluoridation (CWF) and intelligence (IQ) in New Zealand. Methods. We conducted a study of a general population sample of those born in Dunedin, New Zealand, between April 1, 1972, and March 30, 1973 (95.4% retention after 38 years of followup). Residence in a CWF area, use of fluoride dentifrice and intake of 0.5milligram fluoride tablets were assessed in early life (prior to age 5 years); we assessed IQ repeatedly...
