One-liner
A stair-step survival curve is a Kaplan-Meier curve; vertical drops are events.
Rapid recall: Kaplan-Meier vertical drop?
Event occurred.
Rapid recall: censored data?
Incomplete follow-up, not death.
Extra practice
On a Kaplan-Meier curve, a participant is lost to follow-up at year 3 without having the event. How should that be interpreted?
Reveal answer & explanation
As censored data , not as an event/death.
