Exclusion of neither pre-2008 nor pre-2016 lifespan data through left-censorship modified the observed lifespan demographics of H. glaber. A The number of naked mole-rats observed (y-axis) at each age (x-axis) for four datasets: (i) the original data set presented in (Ruby et al., 2018) (pink); (ii) that data set left-censored on January 1, 2008, as presented in (Ruby et al., 2019) (yellow); (iii) the full data set compiled in 2021 for this manuscript (green); (iv) that data set left-censored on May 17, 2016 (navy), i.e., data collected after the compilation of data for (Ruby et al., 2018). B Kaplan–Meier survival curves starting at T_sex (183 days; red) for the four demographic data sets, as colored and described in panel A. C Mortality hazard estimates (y-axis) across each of the lifespan bins from panel B (indicated on the x-axis), for each of the four demographic data sets, as colored and described in panel A. Horizontal bars indicate hazard estimates, and vertical bars indicate 95% confidence intervals.
