Example sentences for: unexposed
How can you use “unexposed” in a sentence? Here are some example sentences to help you improve your vocabulary:
Person-years in unexposed controls were calculated as: (total number in the control group) × (the number of years from age 40 to the average age of the group).
The observed number of "incident" cases of AR or MR in the exposed group was calculated as the total number of cases minus the number expected at baseline (estimated from the prevalence in the unexposed control group in each study).
Raw data from each study is given for mild or greater AR in table 3and for moderate or greater MR in table 4. Estimates of unexposed incidence of AR and MR utilizing data from the control groups in these studies yielded values approximately 50% higher than estimates from the Framingham study; 0.555% per year for mild or greater AR and 0.219% per year for moderate or greater MR. To provide conservative estimates of relative risk, these rates were used to calculate the expected number affected (given the duration of exposure in each study) for Poisson analyses in tables 5and 6. Estimates of "incident" cases and relative risks based on person-years are also given in tables 5and 6.
Note that pooled incidence rates for the unexposed were not used in this analysis (so as not to inflate power); rather, each study provided its own estimates.
Our findings suggest that these estimates are strongly biased toward the null because of counting background, prevalent cases as incident cases in both exposed and unexposed groups (a form of nondifferential misclassification) and not considering the remarkably short period of exposure during which most observed differences in prevalence arose.
