Table 1 Lifespan data of Macrostomum lignano in three replicate cohorts (1–3).

From: Demographic analysis reveals gradual senescence in the flatworm Macrostomum lignano

Replicate N(censors) Median lifespan (days) 90th percentile (days) Maximum lifespan (days)
1 100 (0) 197 347 672

3 100 (9) 220 409 more than 745
  1. All replicates initially started with 100 individuals (N). Individuals that died due to age-independent infection were censored. Median lifespan and 90th percentile are the ages at which 50% and 90% mortality are reached respectively, while the maximum lifespan is the age at which the last survivor of the cohorts dies. At the day of submission the last 4% survivors of replicate 3 were 745 days old, and therefore the maximum lifespan of replicate 3 could not yet be determined.
