Single Person-Time Rate
The PersonTime1 module of Open Epi is used to analyze data based on length of exposure, persons exposed, and a count of the event being measured. This method of analysis is frequently used in cohort studies and clinical trials. Person time is frequently expressed in person-years, although person-hours, days, or months will work just as well. Results include the rate per 100 person-time units and confidence limits using several methods.
