Survival curve for small Zambian mole-rats.
Kaplan–Meier survival curve for small Zambian mole-rats (Fukomys anselli and Fukomys anselli x kafuensis) that reach the same age as that used as a starting point in Ruby et al. (2018); 95% confidence intervals for the Kaplan–Maier curve and animals at risk are included, as suggested by Pocock et al. (2002). Dotted lines represent median survival after onset of the study at 0.5 years. (A) Original data from 339 animals; median survival after 0.5 years, 7.99 years (95% CI, 7.04–9.60 years). (B) Biased data presentation: animals that died before 2010 have been (artificially) deleted from the dataset. Median survival after 0.5 years, 10.80 years (95% CI, 8.82–11.39 years).

Figure 2—source data 1
This xlxs-file contains the lifespan data for small Zambian Fukomys-mole rats that underlie Figure 2A,B.
Each row in the file contains data for one individual animal. Columns inform about individual animal IDs, birth date/year, sex, death date, the date on which data for that animal was compiled ('DataDate'), censorship, lifespan (in days) and additional notes whenever specific circumstances for that specific animal had to be reported. 'DeathDate' is empty if the animal was still alive at the time of data compilation ('DataDate'). In such cases, 'DataDate' was used as the date-of-censorship.
