The
Results
tab contains the following elements:
This plot shows the survival rate across the range of observed event time for each individual or sample. The
y
-axis indicates the survival rate and the
x
-axis indicates the event time.
Note
: If you specify a
Group Variable
on the
General
tab, each group is represented by a different color.
The
y
-axis indicates the estimated survival rate for the reference time, 7.5 in this example. You can set the reference time using the
Reference Time for Comparing Survival Curves
option on the
Analysis
tab of the process
dialog
. If you leave this parameter empty, the
median
among all samples is applied.
The
x
-axis in the plot indicates the corresponding groups (
NIC 15
and
Placebo,
in this example). The horizontal line (at 0.9) indicates the overall average. The left panel of the plot shows the result of comparison between groups using Hsu's MCB method. When the two circles are disjoint, the corresponding average survival rates are significantly different (in this example they are not).
You can apply other multiple comparison methods by clicking on the red triangle (circled in blue) and selecting one of the
Compare Means
options (as shown below).
There are certain modeling settings and results shown above the plots. The settings for
predictor
reduction and analysis are listed in lines one and two respectively. The selected predictors are listed on line three. The training set criteria (in this case, Harrell's C Statistic
1
, is listed in line four. The reference survival time applied to the box plot on the right is shown in line five.
In this example, the points on the
box plot
are the survival rates of event time at 7.5 on the left
survival plot
.
