In Table 1 of their article, Cheng et al presented the cumulative incidence of 55 and divided this number by the TB incidence per 100000 persons/year in the general population during the study period (8.6/100000/year), resulting in an incidence rate ratio (calculated by the authors) of 6.3 (55/8.6). Cumulative incidence is defined as the probability that a particular event, such as occurrence of a particular disease, has occurred before a given time.Cumulative incidence is calculated by the number of new cases during a period divided by the number of subjects at risk in the population at the beginning of the study.Measure of disease frequency during a period of time,"A glossary for evidence based public health",https://en.wikipedia.org/w/index.php?title=Cumulative_incidence&oldid=951497929,Short description is different from Wikidata,Creative Commons Attribution-ShareAlike License,This page was last edited on 17 April 2020, at 13:28. This is also the same as the ratio of the number who played sports to the number who did not. The ratio between two cumulative incidences (risk in exposed divided by risk in unexposed) gives the relative risk (or risk ratio). Cumulative Incidence is also known as the incidence proportion.

Claudia C Dobler, Cumulative Incidence and Incidence Rate Ratio for Estimation of Risk of Tuberculosis in Patients With Cancer,To the Editor—In their systematic review and meta-analysis of the risk of active tuberculosis (TB) in patients with cancer, Cheng et al evaluated the cumulative incidence of TB among patients with cancer and used this information together with annual country-specific TB incidence rates from the World Health Organization to estimate the incidence rate ratio of TB in patients with cancer compared to the general population [,A further important limitation that is not mentioned by Cheng et al in their article is that using the general population as a comparator group without adjustment for important confounders, such as age, will likely result in overestimation of the TB risk among cancer patients in the United States [.The authors’ conclusion that “individuals living in the United States with hematologic, head and neck, and lung cancers had a 9-fold higher rate of developing active TB compared to those without cancer and would benefit from targeted latent TB screening and therapy” must be questioned in light of these methodological concerns.Oxford University Press is a department of the University of Oxford. r survival cox-model incidence-rate-ratio competing-risks.
