Adverse Events Risk Report

This report screens all adverse events and calculates and generates forest plots of risk differences, relative risks or odds ratios. It reports each subject only once per adverse event regardless of how many incidents of the event occur.

Report Results Section

Running Adverse Events Risk Report using the Nicardipine sample data for risk differences generates the report shown below.

The Report contains the following elements:

Risk Plot

This section contains the following elements:

• One Dot plot showing the percentage of patients in a treatment group who experience the event at least once during the trial period.
• One Forest Plot showing the risk difference measurements with 95% confidence intervals for all of the adverse events exhibited by the subjects. In the plot shown below, the risk difference with unadjusted 95% confidence intervals1 for each event are presented. Events shown are restricted to the specified group or term level, when specified.

Tabulate

• The table presents an alternate view, listing the subject counts experiencing an event and the respective percent of subjects (in parentheses) on each treatment arm, as well as the risk difference and 95% confidence interval (in parentheses) for the terms (or those terms falling under selected groups, when specified).

Options

Data

Use the widgets on this panel to customize your analysis.

Term Level

Term Levels are determined by the coding dictionary for the Event domain of interest, typically these levels follow the MedDRA dictionary. Use this widget to specify how each adverse event is named and the level at which the event is considered. For example, selecting Reported Term for the Adverse Event reports the event specified by the actual event term as reported in the AE domain . Refer to Term Level for more information.

Include serious adverse events only

By default, all events are included in the analysis. However, you can opt to include only those considered serious. Checking the Include serious adverse events only widget restricts the analysis to those adverse events defined as Serious under FDA guidelines.

Event Type

Analysis can consider all events or only those that emerge at specific times before, during, or after the trial period. For example, selecting On treatment events as the Event Type includes only those events that occur on or after the first dose of study drug and at or before the last dose of drug (+ the offset for end of dosing).

Ignore available treatment emergent flags

If you choose to Ignore available treatment emergent flags, the analysis includes all adverse events that occur on or after day 1 of the study.

Risk Measurement

You have the option of calculating either the Risk Difference, the Relative Risk, or the Odds Ratio as the Risk Measurement.

Display Risk Difference as:

Use this widget to specify the difference between the risk of an event in the treatment arm and the control arm as either a percentage or a proportion of the total subject population. This widget appears only when you select Risk Difference as the Risk Measurement.

Sort Risk Report plot and tables by:

Use the Sort Risk Report plot and tables by: widget to specify how the rows in the Risk Report plot and tables are to be sorted.

Treatment Value for Sort by

Use this widget to specify the treatment value to sort the plots and tables by. This is especially useful when there are multiple treatment regimes. Refer to Treatment Value for Sort by for more information.

Include volcano plot

Check the Include volcano plot box to include a volcano plot in the report. The volcano plot is added to the top of the report. An additional option for specifying the alpha value is also surfaced when this box is checked

 

Alpha

The Alpha option is used to specify the significance level by which to judge the validity of the missing findings data generated by this report. The meaning of alpha depends on the adjustment method that you select. Alpha can be set to any number between 0 and 1, but is most typically set at 0.001, 0.01, 0.05, or 0.10. The higher the alpha, the higher the error rate but also higher the power for detecting significant differences. You will need to decide on the best trade-off for your experiment. This option is surfaced only when the Include volcano plot box is checked.

Additional Filters - Adverse Events

This filter lets you restrict your analysis to only those subjects that meet specific criteria at the AE domain level. See Adverse Events for more information.

These filters enable you to subset and view subjects based on demographic characteristics and other criteria. Refer to Data Filter for more information.

Note: Filter specifications are reapplied when any widget options are changed.

Methodology

Patients are assessed for each adverse event they experience and Percent Occurrence and Risk Difference are calculated for each event by treatment group. Percent Occurrence is simply the percentage of patients in a treatment group who experience the adverse event at least once during the trial period. Risk difference is calculated by subtracting the number of patients exhibiting the adverse event in the control group from the number of patients exhibiting the event in the treatment arm. Relative Risk or Odds Ratios may also be calculated.
