Mortality Time to Event

Mortality Time-to-Event groups clinical mortality results by treatment arm and generates Kaplan-Meier survival curves with associated statistics.

Report Results Description

Running this report for Nicardipine using default settings generates the report shown below.

Product-Limit Survival Fit

Contains a Kaplan-Meier time-to-event analysis and associated statistics

One Survival Plot.

This analysis compares the time until the last disposition record. Otherwise, subjects are censored at the reference end date (RFENDTC).

See Survival Plot for more information.

Summary Statistics

Contains tables of summary statistics for the survival of the study subjects.

Hazard Ratio Plots

Displays Hazard Ratio Event Plots with 95% confidence intervals for each of the following demographic subgroups: overall, gender, race, country, and study site identifier.

Options

Data

End Date Variable to Use for Censoring

Use the End Date Variable to Use for Censoring option for specifying the end date for censoring. Options include the reference end date (selected by default), date of the last treatment, or the date of the last disposition record.

Click to open and view the Review Subject Filter.
Click to specify Derived Population Flags that enable you to divided the subject population into two distinct groups based on whether they meet very specific criteria.

By default, time is measured in days. However, you can change the Time Scale to measure time in weeks. This option is useful for assessing report graphics for exceptionally long studies.

You can opt to assess interventions across the entire study (specified by default). Alternatively, you can specify a Begin Time and an End Time to restrict the analysis to a specific time interval.

Methodology

Deaths are determined using records from the disposition dataset where the term (DSDECOD) is either DEATH, DEAD, or DIED and the study day (DSSTDY) is greater than or equal to 1. Subjects with missing censor date information are removed from the analysis. Notes are displayed at the top of the report for what censor date variable is used and how many subjects were removed due to missing censor date information.

To produce the hazard ratios, the preference for control level must be set to a level other than None. Any subgroups in the hazard ratios that cause a convergence issue are removed from the analysis and a note is displayed under the plots for which subgroups were removed.
