Survival tables offer no choices for data entry

When you create a survival table, you have no choices for data entry. You don't enter error values. Instead, Prism computes the SE or 95% CI of survival when it creates the survival curves from raw survival data. Learn more about entering survival data.

If you want to enter survival fractions with SE values computed elsewhere, create an XY graph. In this case, Prism will not be able to compare survival curves.

Survival graphs can include error bars computed as standard errors or as confidence interval. To change: Double-click anywhere on the graph to bring up the Format Graph dialog and then go to the third "Graph Settings" tab.

If you plot the 95% confidence interval as confidence bands, you can fill or color the area between the bands.
