The incidence proportion of injured students was 0.
1-3,10,23,24) The incidence proportion of injury in our study was slightly greater, with 61/71 (85.
Epidemiologic incidence proportion
(also referred to as clinical incidence) and related 95% confidence interval (95% CI) was calculated for each season as the proportion of the number of new players injured during a season relative to the total number of players without injury at the start of the season (10).
Although quite rare -- with an incidence proportion
of approximately one per 1,500 of the population -- the disease can be disfiguring, extremely painful and difficult to treat.
Attributable risk was defined as the incidence proportion
in the exposed group minus the incidence proportion
in the UNX group, which was adjusted for differences in the distribution of covariates between groups.
The prevalence, incidence rate, and incidence proportion
calculations were also performed (23); the formulae are shown in the Appendix.
Evaluated in cross-section, this is a cumulative incidence proportion
among cohort members who have survived to the age of assessment --i.
To calculate coccidioidomycosis incidence proportion
in the prisons, we derived coccidioidomycosis case counts from a surveillance system implemented in California prisons in 2007.
Three measures of disease incidence are commonly used in incidence studies (Pearce 1993): the person-time incidence rate, the incidence proportion
, and the incidence odds.
Only a single case was reported in Mono County during 1988-1992, but the small population size resulted in a relatively large incidence proportion
Differences between incidence proportions
were analyzed by using the 2-tailed 2-proportion z-test with a 95% CI, and nonparametric bootstrapping was used to construct a 95% CI for the relative increase in risk.
History is a database that holds association rules and their incidence proportions
