Invitation to complete quick survey to improve Kaplan-Meier plots (KMunicate)
We would like to invite you to take part in this quick survey led by the MRC Clinical Trials Unit at UCL to improve Kaplan-Meyer plots:
The standard way to present time-to-event data, such as survival, is with Kaplan-Meier plots. These are formatted by journals and reported in a number of ways, but we find they commonly lack some key information.
The key problems are:
- Expressing how many people are contributing data at any point in the graph, including the pattern of censoring
- Expressing that the uncertainty of the estimate increases over time
We have some initial suggestions on how to improve Kaplan-Meier plots, but we need your help to know which would be the most useful and most acceptable to a wide audience.
Invitation to a short survey
Could you take our short survey of 9 meaningful multiple choice questions?
You’ll be asked to compare standard and alternative graphs, using data from one of three RCTS, chosen at random when you follow this link: http://www.ctu.mrc.ac.uk/resources/Kaplan-Meier/index.html.
Please complete the survey in one attempt as we cannot guarantee you will return to the same trial.
The survey will be open until early in Jun-2017.
The findings will be written up for publication in a peer-reviewed journal and also introduced in an active poster session at the joint SCT & ICTMC 2017 conference in Liverpool.
We are interested to hear from anyone who looks at survival curves and are casting our net as wide as possible. Please forgive us if you have already received an invitation through another means.
If you have colleagues you think would be interested (including clinicians, journal editors, operations specialists, systematic reviewers, regulators, statisticians and trialists), please feel free to forward our invitation and link.
Thank you for your time. The Project team:

What a great survey, I love the questions!
This is really interesting.

Really great questions.
Done it already!
Done it as well, but the results are really surprising. I love it so much!
