Letter to Editor: Interpreting Incidence from Hospital Based Data Retrieval: A Comment on Incidence and Determinants of Stillbirth amongst Parturients in Two Hospitals in Southern Nigeria

Abstract

This point is further clarified once we have a look at the results. The authors have provided fetal mortality rate as 0.6% (as a percentage), whereas incidence being a rate, should have been quoted just as 6.1/1000 live births and not as percentage. As per the definition of incidence given above, incidence rate refers during a given time period in a specified population at risk. The measure most often used is person years and not percentage.[2]
