Extract data from a Kaplan-Meier plot

I describe how to extract (approximate) patient level data from a Kaplan-Meier plot using the algorithm of: Guyot, P., Ades, A., Ouwens, M.J. et al. Enhanced secondary analysis of survival data: reconstructing the data from published Kaplan-Meier survival curves. BMC Med Res Methodol 12, 9 (2012). https://doi.org/10.1186/1471-2288-12-9 (link to R code in paper) and using WebPlotDigitizer: Author: Ankit Rohatgi Title: WebPlotDigitizer Website: https://automeris.io/WebPlotDigitizer Version: 4.2 Date: April, 2019 E-Mail: [email protected] Location: San Francisco, California, USA See also https://healthdatacounts.com/2019/12/... The Kaplan-Meier plot I used as an example came from the supplementary material of: Gandara, D.R., Paul, S.M., Kowanetz, M. et al. Blood-based tumor mutational burden as a predictor of clinical benefit in non-small-cell lung cancer patients treated with atezolizumab. Nat Med 24, 1441–1448 (2018). https://doi.org/10.1038/s41591-018-01... I also mentioned the Stata version: Wei, Y., & Royston, P. (2017). Reconstructing Time-to-event Data from Published Kaplan–Meier Curves. The Stata Journal, 17(4), 786–802. https://doi.org/10.1177/1536867X18017...
