Ageing and response to caloric restriction in strains C32 and KA53. a Experimental design for each strain, half of replicates were sampled at 10 days and half at 50 days and half of replicates were submitted to normal food (NF) and half to caloric restriction (CR). This resulted in eight combinations of factors (two strains x two ages x two food levels), each of which consisted of six replicates. b Survival curves for C32 and KA53 in response to caloric restriction and normal food levels. NF = normal food; CR = caloric restriction X-axis = time in days; orange line = survival probability for normal food; orange shading = 95% confidence interval of the normal food survival probability; blue dashed line = 95% confidence interval of the caloric restriction survival probability; CR = caloric restriction; red dashed vertical lines indicate sampling points for young replicates at 10 days, and old replicates at 50 days
