A list of the strains of worms used in this study, the genotype for each strain, and a brief description of functional impairments.

The column indicating #N2 controls indicates the number of N2 animals that served as matched controls for each survival experiment. The #Animals Evaluated indicates the number of animals for each strain that were subjected to anoxia for survival determination. The #Trials indicates the number of independent experiments that formed the basis of survival estimates for each strain. The final column of the table indicates the figure where the survival data appear.

标注为#N2对照组（#N2 controls）的列，代表每个存活实验中作为匹配对照的N2型动物的数量。#受试动物数（#Animals Evaluated）列，代表每个品系中为测定存活率而接受缺氧处理的动物总数量。#实验次数（#Trials）列，代表为各品系生成存活率估算值所依托的独立实验总次数。该表格的最后一列，标注了存活数据所在的配图编号。
