Subject Time Trends
The Subject Time Trends tab is shown below:
The Subject Time Trends tab contains the following elements:
A set of Subject Level Time Trends Plots also known as spaghetti plots
If findings test category (xxCAT) exists (where xx represents the two letter domain abbreviation -- for example, LB), these plots are first ordered by xxCAT. Next, if findings test subcategory (xxSCAT) exists, plots are secondarily ordered by xxSCAT. If xxCAT is missing, plots are ordered by test short name (xxTESTCD), which is required. Findings tests with a missing xxCAT value are assigned to the “OTHER” category.
Note: Findings tests with a missing numeric result (xxSTRESN), as well as those taken on only one day, are excluded from these plots.
Tip: You can collapse categories (and simultaneously exclude them from any report that you create) by clicking on the gray triangles located to the left of the category labels.
Each plot displays the measurements taken across time for each subject in a study for a quantitative findings test. The value of xxTEST is displayed in the outline box for each plot and the test short name (xxTESTCD) is displayed along with the measurement units (where applicable) on the y-axis. The y-axis can represent the observed test result, the change from baseline, percent change from baseline, or percent of baseline, depending on the selection made for the Plot findings measurements as: parameter on the process dialog. Time, as either Study Day, Study Week, or Visit, is plotted on the x-axis (according to yourTime Scale selection). Time trend lines connect the points of measurement; each marker point represents the findings measurement for each subject at the measured time point. If multiple measurements were taken for a subject on the same Study Day, Study Week, or Visit, the point represents the mean measurement for that subject.
The y-axis can optionally be displayed with log scaling (this is very useful for interpreting laboratory findings). For the LB domain, you can also choose to draw reference limits by checking the Show ULN and LLN reference lines for lab tests option on the dialog. If there are multiple reference limits for a lab test, the maximum ULN (as measured by LBSTNRHI) and the minimum LLN (LBSTNRLO) are displayed.
The time trend lines are interactive. Selecting a line selects that subject. You can then use the drill down buttons to profile, cluster, or show selected subjects, or create a subject filter to do further analysis only with the selection of subjects. A Data Filter is also included on this tab that can be used to select subject time trend lines based on subject demographic variables.
