How can you use “person-years” in a sentence? Here are some example sentences to help you improve your vocabulary:
For each diagnosis of interest, incidence rates were calculated for each BMD group by dividing the number of cases of disease by the number of person-years of follow-up.
Indeed, an older study based on Utah data covering the years 1971 through 1985 found that the age-adjusted (to the 1970 US standard) prostate cancer incidence rates per 100,000 person-years were 76.
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.
Using this criterion, the 152,435 encounters for LRI were reduced to 106,670 distinct episodes of lower respiratory infection, giving an overall annual incidence rate of episodes of LRI coming to medical attention of 93/1,000 person-years.
Despite its decline as a result of widespread antiretroviral therapy and chemoprophylaxis, PCP has remained a common complication in patients with HIV infection [ 2 3 ] . In a prospective multicenter study of HIV seropositive patients, for 79% of those with a CD4 +lymphocyte count < 200/μL receiving PCP chemoprophylaxis, the rate of first episode PCP was 3.3 per 100 person-years [ 4 ] . Although actual data were not available, high rates of noncompliance with and lack of access to antiretroviral therapy and chemoprophylaxis were likely in our study population, which included a significant number of medically underserved patients without perceived risk for HIV.
