Calculation of the crude incidence (risk) of incident events by week or IDs (or rates) of incident events, expressed usually in counts per 1,000 patient-weeks of treatment (or observation), provide estimates of the 'real-world' frequency of reported events.
Table 1 shows the total population, the number of incident events and age standardised incidence rates for each year group stratified by sex, age and deprivation group.
Analyses of drug-related adverse events that occurred at an incidence rate of at least 0.2 incident events per 100 patient-years in either treatment group are in Table 7.
Specific serious adverse events, irrespective of the relationship to study drug, that were reported with an incidence rate of at least 0.2 incident events per 100 patient-years in either treatment group are in Table 8.
In the prespecified analysis adjusting for exposure to treatment, the incidence rate of vascular events was 3.5 incident events per 100 patient-years with sitagliptin compared with 4.8 incident events per 100 patient-years with glipizide.
We constructed the 95%% confidence intervals of the incidence rates based on the assumption that the observed incident events followed a Poisson distribution.
The Kaplan-Meier survival functions by region for CVD incidence are shown in Figure 2. A similar figure showing prevalent and incident events combined is presented in Figure 3.
Every data structure reporting on history or incident events is a 32-bit word.
They are referred to 3 months of 2005 (January, April and August) for the amount of 237 incident events.
The explanation of these apparently divergent results probably lies in the limited number of incident events with non-zero values for the related variables.
These models have been developed and tested using a common incident data set, including 237 incident events, for allowing a direct comparison of the models' prediction ability in the various incident situations.
