Incidence density rates were consistent with cumulative incidence, with a rate of 26.5 per 1000 person-years between the ages of 5 and 14 years (Table S3 in the Supplementary Appendix).

We conducted a surreptitious, prospective, cohort study to explore how often physicians nod off during scientific meetings and to examine risk factors for nodding off. After counting the number of ...

Testosterone treatment in men with hypogonadism improves bone density and quality, but trials with a sufficiently large sample and a sufficiently long duration to determine the effect of testostero ...

The incidence rate describes the frequency at which new events occur. It is used in many industries to project incidents during project planning or product launches.

Case incidence reductions were attenuated in suburban and rural counties with population density below 200 people per square mile (exhibit 4, appendix exhibit S8). 25 ...

The incidence of deep vein thrombosis was described as rate (number of deep vein thromboses per 1000 patients with a peripherally inserted central catheter) and density (number of deep vein thromboses ...

The comparison of incidence density between the two treatment groups were expressed as an incidence density ratio (IDR). The 95% confidence intervals were calculated assuming a Poisson distribution.

“Adults with incident peripheral neuropathy were matched (on age, sex, general practice, and calendar time) with up to 4 controls by using incidence density sampling selected from a cohort ...

Three random age- and sex-matched controls per patient were sampled from the Total Population Register using incidence density sampling.
